The consoles will end up very similar in terms of tech and ability. I imagine this is just that they're still finalising stuff or hadn't talked explicitly to the devs Jason spoke to, but the end result will be much the same.
i think most those games hide loading in the cutscenes, which is still equal to no loading but..
Uncharted just has that one long ass loading in the beginning.
I prefer a long loading screen at the beginning of the game and then none while I'm playing. Especially with sleep/restore mode, so I can pick it back up the following night without needing to load.
