We're just a few days away from the start of Google I/O, and as such we're starting to hear more and more rumors about what's planned. Google has already leaked out details on the name of forthcoming Android update, and now Gizmodo Australia has allegedly received a "training document" that details the exact specs and cost of the long-rumored Nexus 7 tablet. As we heard before, this tablet appears to be an Asus product — specs include a 1280 x 800, 7-inch display, 1.3GHz Tegra 3 processor, 1GB of RAM, and a 12-core GeForce GPU. It's also reportedly priced very aggressively — the 8GB version will come in at $199, with a 16GB version available for $249.

Unfortunately, Gizmodo hasn't published anything from this training document aside from the image you see below, so we'll have to wait until later this week to see if these specs are real — but we reached out to Gizmodo and were told that they're confident in the source, and that he or she has contributed before. We had previously heard that Google was ready to launch its tablet in July, so the timing works out — Google I/O kicks off on Wednesday, June 27th, and we'll be there live to cover all of the announcements.
