Billy for sure for me. Im also suprised that Jill isn't in this game. Dunno if this will be the last game in the main franchise or w.e but itd be awesome (as well as immensely cheesy, but thats part of RE IMO) to have all the major characters make some form of appearance in the final game.
Im also just really curious what Rebecca is doing now as well. Claire is with that other group that's anti BOW but doesnt fight them with violence or w.e. Jill im guessing is still recovering. Sheva was probably just a one shot, but I liked her. Barry is presumably in Canada with his family. Still really wanna see Billy again. What about everyone else? --- Go beyond the impossible and kick reason to the curb!
I can't lie, Albert Wesker. He is one of my favorite villains of all time and I wouldn't mind him coming back out of no where. --- "Can you draw two M&Ms fighting with katanas?" -Me http://img16.imageshack.us/img16/9606/mmfight.png -aDubiousNotion
Pretty much every character who's been absent since 1998. Claire, Rebecca, Billy, Barry. Ffs, they brought Sherry back. I could even go for some Carlos or Hunk. At least mention that they're alive? lol
