I'm loving the possibility of the Sony Gem (if that's really the name).
So many PS3 games, both exclusive and multi-platform, could be remade with motion controls. The PS3 could pretty much be the Wii HD that we never had. Natal has some interesting possibilities right now, but I'll have to see how it's implemented in big name titles like Fable 3 and Halo: Reach before I form my final opinion on it (sorry, flip-and-swing-your-arms Dodgeball looks pretty dull). As fo the Wii Vitality Sensor, what does that even do?
