Honestly, I'm surprised nobody mentioned this before. But what the PS Move is, is a motion controller that's supposed to be extremely accurate and can be used on plenty of games, including previous titles prior to the Move's launch date.

That link right there takes you to the Move's site where you can look at videos and find out more about it.
As for my thoughts, I want this. =D Nuff said.
Thoughts, questions, concerns?
