I already have a Wii Remote and will actually be buying both Natal and Move.
But I voted for PS Move, as I'm more excited about it. In my opinion Move combines the best from both worlds, Wii Remote and Natal. It has a real motion sensing controller like the Wii Remote with "what we in the future call "buttons"", allowing for fast reactions and sensitive controlling. And it has a camera with a multi-array microphone, so all games for EyeToy and many games for Natal can be implemented for Move as well.
On the other hand, I'm getting more and more sceptical about Natal. Natal sounded fantastic when it was first announced, but meanwhile it's getting more and more obvious that Natal has a whole number of disadvantages and is just not what the average gamer wants.
