Next Apple's iPad Mini, the 32GB Google Nexus 7 may be the next worst kept secret in tech. After sites first began to report the existence of a 32GB Google Nexus 7 tablet, numerous claims flooded the Internet over the last week purporting to have already bought and/or received the device. First, Staples accidentally sold the tablet. And now it looks like Office Depot is already selling the product ahead of Google's big event Oct. 29.

Office Depot's page for the 32GB Nexus 7 just went live this morning, Oct. 25. There is no picture of the device and it's only available through in-store pickup. But, who cares? It's still available right now and costs only $249.99. You can buy one today and pick up it at the store.

Somewhat confusingly, Office Depot is still selling the 16GB Nexus 7 for the same price as the newly revealed 32GB model, although, we'd expect the price to drop to a more manageable $199 once Google's Monday event rolls around.

Google's 8GB Nexus 7 is currently unavailable on Google Play, possibly hinting at the product's removal from the Nexus lineup after the 32GB is officially announced. As numerous sources note, this could be an example of Google aping Amazon, as the online retail giant typically discontinues products a few days before they're to be replaced.

The Nexus 7 tablet's $249.99 price tag should prove seductive to consumers, especially considering Apple priced its hotly anticipated 7.9-inch iPad Mini at $329.

"We were hoping the price would be at least a little lower given its competition is situated as low as $99, with many starting in the $199-$249 range," Barclays Capital analyst Ben Reitzes said.

Strategy Analytics analyst Peter King, who had also been expecting a $300 price point, says the extra $130 will be enough to sway some buyers toward the Nexus 7, the Kindle Fire family or even Barnes & Noble's $229 Nook HD.

32GB Nexus 7 AND 3G Nexus tablets

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.

THE 8GB Google Nexus 7 tablet is now mysteriously "unavailable" to buy from both the U.S. and U.K. Google Play stores, which may quietly confirm rumors that Google will launch a 32GB model at its Android event next week.

Customers wanting to buy the 8GB tablet, which was launched back in July, are now greeted with a "coming soon" sign where it previously showed "add to cart." Users are instead left with an option to submit their email addresses and be notified by the website when the model becomes available again.

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."

The Nexus-brand tablets expected to be released by Google will compete directly with Apple's iPad Mini, and Amazon's Kindle Fire HD. And while the tablets are dwarfed in size by the Microsoft Surface's 10-inches, both tablets are expected to be sold well-under the $499 price point.

Although the machines are not as powerful or bulky as the full-sized iPad and the Microsoft Surface, many consumers have opted for 7-inch tablets due to concerns over portability and pricing.

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.

A member of the Android Central forum, the highly credibly named Stonerman34, leaked the information that the Nexus 7 has a release date of Oct. 29.

Further evidence of a Oct. 29 release date comes via Droid-Life, who claim a reader "took the item number that leaked over the last week (#100604), contacted their sales department, and was able to purchase the [32GB Nexus 7]."

The reader was then called by Staples who said they had to cancel his order due to contract details with Google, and he was told that he could re-order on Oct. 29.
