I think I got my WDTV Live for 60 bucks and there are plenty of Android media boxes for 99 bucks. There's nothing new about what you are asking about. Some like the OOYA overpromised and died. (You can read them yelping "I'm not dead yet.")
Look. Yawn, move on?
The system will be powerful enough to have a whole android system running on it.
Which will let you download apps and all that good stuff.
It will also have XBMC for all your movies and shows.
Lastly, it will also have emulators and such for you to play some 3-D and classic games on your TV.
Comes with an amazing wireless remote that has a touchpad and can fit in your pocket.
The Ultimate Home Media. Would you pay over $100 for this type of home TV media centre?
P.S the TV system will also be somewhat pocket sized for portability.
