400mm is a little bit different. I guess some people will pay that much for the new version just because it's 28% lighter so they can finally handhold the lens. same as the 600mm and maybe the 500mm.
if they raise the price of older version 10% and reduce the new one 10%, that would make a lot more sense to me.
