Not really in terms of it would make me get a 360, but I've very interested in it as an input device and would definitely explore it if they also make it available to hook up to your PC.
It may be because I'm so used to Wii but I'm currently in the unconvinced camp around needing some buttons. I just think Natal's true range of options if MS really stick to having no controller at all will be fairly limited - for example without buttons how would you realistically move a character forward, look around and shoot all at the same time?
Mind you, I fully expect MS to hype on 'no controller' then lean on using existing controller in conjunction with Natal when it suits.
Playing Devil's Advocate, if Natal does prove to come with some great new gaming experiences then I might well "Jump In" so I guess right now I'm more of a 'Maybe' than anything else.
Try to be reasonable... its easier than you think...
