In this place, it is inevitable. People will judge unfinished product based on the first screenshots, regardless of how little even the BEST screenshots truly represent the final game, running in realtime 720p/1080i/1080p @ 60fps.
I've heard all the excuses, "What else are we supposed to do when all we have is screenshots?" This isn't inherently the issue.
The problem is when people take that first step, then go fanboy-****ing-nuts, and writeoff the game completely. Then they act all ****ing surprised when the finished product comes out and stammer "Where did THIS come from!?"
Open your eyes: posters that are harping on this game or screaming "DOWNGRADE TOTAL" need to reel that shit in just a bit. Capcom is one of the few Japanese developers giving everyone else a run for their money in the NextGen quality department, and DMC ain't no MegaMan Battle Network sequel. I am fully confident this game is going to rock everyone's ****ing socks off both visually and gameplay-wise.
If you are feeling disillusioned because it doesn't exactly match the concept work that was shown last year, then it's time to clamp down on your expectations, because they're starting to run wild. Even then, wait until the game is actually FINISHED. It will probably end up looking just as impressive, only with more than one character on the screen.
