Here's what I'm expecting so far, and it's not confirmed, just sort of a bet:
- No more choices
- Only one ending
- Sense of horror isn't as strong as in the original (even though both RE3s are more action than RE2s)
- Will have inferior animation to RE2
- Will have new weapons but also lack certain old weapons.
- Still no spiders (both because it's costly to rig spiders enough that it won't justify it, and because devs now consider it "goofy")
- Carlos will have a new segment and it'll not be as good as everything else.
- Will also have an unmemorable soundtrack remaster.
- Many puzzles in the original game have been replaced with nothing.
Not to say it'll be shit but all of these detriments are things I expect on top of a game that is more or less the way RE2 was, which is a pretty good game.
