I am..
I have a 720p projector that i used for years... I am pretty sure that i will be buying a plasma, or LED and most likely never use the projector again.. Unless i have a dedicated room, with complete control of the lighting in said room...
Like you said, flat panel TV's are getting bigger and bigger as well as more affordable... As they approach the 90+" size the advantage (huge picture) of a projector diminishes. I think currently as the 80+" flat panels sell for just over 5k$, there will be more and more people shifting away from projectors, especially when the price drops below 5k$..
