Seems to make a big difference, now, to some of the very same people who, only a year ago were touting a 720p 30fps game as the best of last gen. Now, all of a sudden, their inter-active cartoons have to move smoother and be more "realistic". Being an avid retro-gamer I find it some what amusing, and never really gave framerate much thought. Now, in certain quarters, obsessing about it is all the rage. No matter; everyone should have a hobby.
Is there anything wrong with that though ? Don't get me wrong, I agree that many suddenly have a new take on what is "Best" based on their new favoured hardware, but expecting more from next-gen compared to last is expected, yes. Although I'm sure you have some of the loudest, over the top posters in mind, who seem to take such things way beyond what is needed.
