The Verge has a story up about a leaked document they were given that talks about what Android TV actually is and the direction that Google is going to take with it. This is the successor to GoogleTV. A product that I've been a fan of, but because of TV industry politics, half-baked hardware and software, and less than ideal developer support, it's not done so well. Google hopes to change that with Android TV - A much more traditional take on the set top box. This time with apps that people are expecting and no integration with TV. (Thanks for the freak out guys.)
