Based on previous new releases of bodies, how long did the previous model stay available before places like B&H, Adorama, etc... ran out of stock? I'm curious, because I really want to upgrade to a 50D, but I need to sell a rifle of mine first, and so far no one has approached me about it yet. I just don't want it where by the time I have the funds it is no longer available. Anyone have any insight?? Thanks.
