Haven't used Move so I'll refrain from commenting on that, although it seems very much like the Wiimote, which is... well, it's fine, for what it does.
Kinect is an interesting idea that requires far too much space to work properly and still has issues with lag and tracking, but the next iteration will hopefully improve on them (and developers will hopefully have a better idea of how to code for it.) I don't see Kinect being too much use with most games unless they (and it) are heavily redesigned, but I'm happy Microsoft don't appear to be dumping the idea - I think there's a afir bit that can still be done with it.
