Any guesses (educated or otherwise) about when and how much the next full frame body will come out from Canon? I love my XT for it's compact size (and the sigma 10-20 is a great solution to the crop factor at the wide angle end), but the more I use it the more I realize there are times I wish I had a larger frame/viewfinder to work with.
Even if a new FF body is a pro oriented, expensive model, maybe it will drive the 5D prices down so I can pick one up used 

(But hey, the 31st would be OK with me.)
