I read about the re-screening feature which sounds like it will definitely help gameplay be more fun and realistic. I always hated waiting for the screener to finish what he was doing before calling another screen
Gameplay is definitely sounding promising. Even if there's room for improvement in the animations, I keep hearing about how fluid the game feels from people who have played it at E3. I'm still liking the sound of the new shooting mechanics and enhanced meter/feedback, and expanded controls. It may not always look the best, but it sounds like it'll be enjoyable to play. Re-screening is definitely big, too.
