There are really only two types of camera people: The rational sane ones and the irrational loonies - the rational - sane ones wait for the camera to be released, reviewed and commented on by actual users - and also wait to sell old equipment to finance the new purchase until the new camera is vetted by the above - the irrational loonies sell old equipment immediately once the new camera is announced, pre-order the new one a second before they list for sale their old cameras, lens, flashes and hope that the reviews and user comments and their own personal experience once they get the camera supports their hasty (rash?) decision - I don't know about you all - but I'm a bit of a loon - and I'm not talking the feathered kind (sigh).
