Google will debut its new iPad competitive tablet, the Google Nexus 10, codenamed "Manta," possibly with 3G and 32GB versions of the Nexus 7, and a Nexus 4 smartphone at its media event Oct. 29, if a report from tech site The Verge is accurate.

The website has obtained pictures that surfaced on Korean site Seeko, showing what looks like a manual for a Samsung Nexus 10.

Rumors have suggested that the Nexus 10 will have a 10.1-inch screen with a Retina Display-beating screen resolution of 2560x1600 with 299ppi making it probably the highest-resolution screen on any tablet available today.

Google Nexus 10 specs

Sources The Next Web spoke to confirm Google's been working with Samsung on a 10-inch tablet that's currently being called "Codename Manta," which could be ultimately be branded as the "Samsung 10," or "Nexus 10," according to numerous sources. The device runs Google's new Android 4.2 operating system "previously referred to as Key Lime Pie, but is set to retain the Jelly Bean branding," says the website.

Google's tablet will sport a 10.1-inch screen, with a pixel density that is higher than Apple's iPad 3, said Richard Shim, an analyst at NPD DisplaySearch.

The display will be 2,560x1,600 and will have a PPI of about 299, Shim added, confirming CNET's purported specs. If this is to be believed, Google have definitely made it a point to best the iPad's 264 PPI on Apple's 9.7-inch 2,048x1,536 Retina display.

"It's going to be a high-end device," said Shim. A stark contrast to Google's other rumored, lower-end tablet, the $199 Nexus 7, and upcoming $99 tablet.

While the Nexus 10's features certainly impress, perhaps the most intriguing part of all of this is Google's partnership with South Korean tech giant Samsung. Google will partner with Samsung for the tablet, and co-brand the Nexus 10 with the company, as well, according to Shim.

Google is also partnered right now with Asus for its hugely popular Nexus 7 tablet.

If the report is accurate, a co-branded tablet from Samsung and Google would flesh out the company's already beneficial relationship. The companies already co-branded the Galaxy Nexus Samsung smartphone together.

Shim described his information about the 10.1-inch Nexus tablet as "supply chain indications," which typically indicates a high likelihood that the product will come to fruition, according to Shim.

The Google ad Samsung Nexus 10, will have the highest pixel density of any tablet on the market, and will be released in the first half of 2013, according to CNET.

Many sources are reporting Google's Nexus 10 tablet will have a 2,560x1,600 pixel density, which CNET says will "push the display manufacturing tech envelope." That high of a pixel density would place the Nexus 10 at the top of the heap with a higher count than Amazon's 8.9-inch display Kindle Fire HD and Apple's 9.7-inch display iPad 3. It's also higher than the rumored screen specs we've been seeing for Microsoft's 10.1-inch Surface tablets.

"By stuffing that density into a 10-inch screen, the PPI jumps to just shy of 300," says CNET.

"The tablet will be more in line with the pricing of its other products, including the Galaxy Tab 2 10.1 and Galaxy Note 10.1," added the website.

As numerous sources note, the biggest drawback of Google and Samsung's 10-inch tablet is that Google lags well behind Apple in building strong collection of tablet-oriented apps. "An app built for a 4-5" phone screen might look OK on a 7" tablet, but not on a 10" tablet. Google is currently making a push to increase the number of tablet-optimized apps," says Seeking Alpha. 

32GB Nexus 7, 3G Nexus 7, Nexus 4 smartphone

Google is rumored to be launching a 32GB version of its popular Nexus 7 tablet, possibly as well as a 3G Nexus 7 and Nexus 4 smartphone.

Google is reported to finally be revealing the 32GB Nexus 7 Oct. 29, according to The Next web. In addition to the new standard model, the website also claims there will also be a HSPA+ (3G) model.

Several sites had previously reported that a cheaper Nexus 7 was planned for release in the U.K. and U.S. before Christmas, according to a retailer's ad.

TeckComesFirst reported that a U.K retailer, Argos, has advertised a 32GB version of the Nexus 7 in its holiday gift guide. The snippet from the purported holiday gift guide shows a 32GB ASUS-made Nexus 7 priced at £199.99 (about $323).

"In the US, several leaks have already suggested that the 32GB device will be available for around $250," reports ZDNet. "One US Staples Advantage promo was spotted by self-confessed 'Google/Android fanatic' Joe Sanchez, who managed to take a screenshot of retailer's online listing for the device before the page was removed."

According to a recent report from Android Central, it appears that the 32GB Nexus 7 will be available at a price of $249, and will most likely be launched on Oct. 29, the date on which Google has scheduled an event in New York.

"We all know there's a 32-gigabyte Nexus 7 coming down the pike -- very possibly at the Oct. 29 event in New York City. And the box of one apparently has made its way into our forums. We've got one member, KidCuda, saying it's ringing up at $249, which is the current price of the 16GB Nexus 7," reported the website.

Ebook blog The Digital Reader reportedly noticed a listing on the FCC's website for an Asus-made tablet believed to be the Nexus 7 3G. While Asus was careful to hide all relevant information on the paperwork, the device in question is referred to as the "ME370TG" -- the original Nexus 7 is the "ME370T," according to PC World, which seems to suggest the listing is for the 3G version.

The device was cleared by the FCC, which would allow Google to release it just in time for the holiday season.

The LG Nexus 4 smartphone will have a quad-core 1.5 GHz Qualcomm Snapdragon processor and a 4.7-in. display with 1280 x 768 resolution, The Next Web's report indicated. It will also have a 2100 mAh battery, 2GB of RAM, 16 GB of internal storage and an 8-megapixel rear camera. It will run the Android 4.2 mobile operating system, also called Jelly Bean, rather than the next-generation Key Lime Pie which some tech websites have reported, said the website.
