i'm sooo glad i only take photos with my cameras - this thread requires a doctorate just to keep tabs with the science!
Of the options being touted for a new body release, i personally would prefer a 1D5, but suppose 1 Ds4 wouldn't be to unwelcome.
As for what the specs are, we'll not really know until it is released. Given that a 5D2 can handle 21mp with a single Digic 4, i'm sure that 32mp is not too far off for next MP rating, working ISO would more than likely push to 25k or 51k and video - who knows. Having spoken to a person who teaches video at a college, he was more than keen to extol the virtues of DSLR's over full blown pro grade video kit where price is concerned. Tell me Canon haven't worked that one out as well?
