I like WMP, Natal doesn't count, and PS3's wand is still a prototype. But in the end I think WMP'll still look better than PS3's thing, but...if it's in that sexy gloss finish ala PS3 the it wins.
Yea WMP you can actually tilt to the exact degree and is very exact. Then its ps3 which is meh but still looks cool. Natal looks pretty neat but limited.
Natals concept is cool and all, but it couldn't really be implemented into the "(hard)core" titles...noticed how no one uses "hardcore" anymore after Nintendo's 08&09 press conference?
