I'm definitely going to need to figure something out as I swap my 65" DLP for a front-projection system. All of my entertainment stuff is going to be moved around and I have no clue where I might put Kinect. I don't think I am going to cancel my pre-orders but I might just have to give Kinect to my son at least until I figure this out. I think I have a plan for my Wii sensor bar...I think.
You should definitely try hard to figure it out. I'm not a big fan of Kinect at all myself, but imagine being able to have a setup where you are as big as your avatar, basically. You'd interact with the game with life-size rafts and waterfalls.
