While Google has yet to confirm or deny that a 32GB model of the Google Nexus 7 is coming, the accidental sale of the 32GB tablet confirms earlier screenshot leaks showing such a device in Carphone Warehouse's inventory system and on the web site of other retailers. This will be the first holiday season that thew Google Nexus 7 will go head to head against the sequel of the tablet that started the low-priced 7 inch category, the Amazon Kindle Fire 2, and it's higher-end Amazon Kindle Fire HD. Considering that there is no microSD slot for expanding memory on the Google Nexus 7, the 32GB model would certainly see a good share of buyers come its way.
The 8GB model of the Google Nexus 7 is priced at $199 while the 16GB version is tagged at $249.00. The 32GB model could come in at or slightly below $300.
