The game looks great - and that's way more important than pushing 1080p or 100.000+ polys per character just for the sake of it, imo.
If you really NEED to discuss the drop to 900p (if that's actually true) as a downgrade, I'd be way more interested in the question of what it potentially tells us with respect to XBOX One's ROP and memory system "balance" than with respect to a game developer's quest for maximizing the perceived visual quality of their game ... the fact that MS openly said that boosting overall GPU clocks (which includes a boost to ROPs and embedded RAM) seemed more effective to them than just adding more shader power (by potentially unlocking CUs deactivated for the sake of yields) was very telling, though.
