Bloomberg is reporting that Google is in fact planning to show off a $199, Nexus-branded Asus tablet at its I/O developer conference this week. The 7-inch tablet has been rumored for months, and will reportedly be the first device to show off Google’s new Jelly Bean operating system. Two days ago Gizmodo Australia posted images and specs it claims to have gleaned from a training manual, claiming the device will have a 1280 x 800 display, a 1.3GHz Tegra 3 processor with its 12-core GeForce GPU, and 1GB of RAM. While the news is definitely interesting, it's not official until Google gives the word, so be sure to check back tomorrow for up-to-the-second liveblog coverage of I/O.
