Much bigger IQ jump than I expected with 900p to 1080p. These screens only make the 720p v. 1080p threads that more mind numbing. I still don't understand how a few months ago when it was just simply a given that everything MS and Sony were going to throw at us was going to be 1080p 30/60fps. It was so expected of this gen, journalists immediatly brushed it aside as it was not even worth discussing and some how even insulting as a bullet point in any developer press conference.
Now the cards are being dealt and we all have to pretend not to notice or we are pedant wankers, or if we have the ability to both tell the obvious gaps between 900p and 1080p, let alone 720p to 1080p, and that we, *gasp* prefer having higher resolutions to support the native res of our HDTVs. What a bunch of fuckwads we are!
PS - I don't own either new console, but all of my displays in my house, PC and TV are 1080p and I don't have glaucoma so I appreciate games at that resolution. It has made jumping between PS3 and PC hard. I was expecting/hoping to leave that gap behind with the console refresh.
