More details are coming out on how Google TV could work, first it looks like it not going to be a replacement for existing boxes from providers but rather a box that be inserted between the providers box and the TV via HDMI in and out. Google would then add web capabilities to the content and of course they will be collecting usage data. While this looks a good way of expanding the capabilities of cable operators boxes (which often with very poor UIs) it does seem a risky strategy to induce Google in to the home, once a Google box was connected to the TV I could see the cable operator being cut out of the loop.
I don’t think Google really need the cable companies, one internet connected device could be all that is need in the future, things like Boxee and of course Windows Media Center are all we need
