Personally, I don't know for sure if I'm buying ANY motion controller any time in the near future. I already have a Wii and, despite it not being very precise, I feel like I've already been there and done that.
With that said, I have absolutely no interest at all in getting the Playstation Move. I just don't find it appealing at all. Nothing about the Move or it's games make me feel like I'll have fun with it. Again, if I didn't already have a Wii (and I wasn't already tired of motion control), I guess I'd be more excited.
As for Kinect (and I know this isn't a Kinect thread), I do have somewhat of a passing interest in that technology. The voice controls and the controller free tech have me curious. I have to see some compelling software for it, though. If anything, I'd get "Kinectimals" for my little girl and it seems a lot less intimidating to buy the one Kinect device when compared to all of the gadgets that I'd need to get the most out of Move.
For now, I'll use a Wii for my motion control needs and I'll fire up my PS3/360 for my awesome graphics needs. Right now, I don't feel the need for the two to cross.
Wii- Definitely (with Wii Motion Plus, a possibility in the future--but not likely)
Kinect- Slightly possible.
Move- No interest whatsoever.
