I still need more character reveals. I'm hoping if Crash and Spyro are announced it's their original naughty Dod/Insomniac selves. Not the "Steve-O"/Elijah Wood versions.
I also wouldn't be surprised to see a few Final Fantasy characters break in. It did have a Sony Exclusive stint for a while so Kingdom Hearts may make it in too. I'd say Sack Girl is a given too.
