Project Natal looks amazing. That guy on GameTrailers Bonus Round brought up a good point about the problem of no controller -- assuming the accuracy is there, you can then incorporate any real life item into the game. It may still need buttons, but maybe it's so accurate it can see you pulling a trigger? And maybe it's accurate enough to pull off the Red Steel 2 type sword fighting with any ol' stick you have laying around.
I think something with buttons will probably be needed for many games. But that's old tech and can be easily added.
It's still early, and I think this will be more of a next-gen thing for Microsoft. But I am damn glad someone is giving Nintendo a run for their money. It cements motion control as a real-deal for the future, and it creates competition.
How awesome would a combination of the Wiimote and Natal be?
