Well I'm guessing the characters that won't get in will be put in if there is a high demand for them like Crash Bandicoot.
so if the game does well in sales maybe that's what those other companies are weighting for plus the demand for there characters.
So will we get more than just a couple characters because the possibility of a lot of DLC characters could be quite high.
Team Ubisof Rayman,The Prince and an Assassin
Team Activision Crash Bandicoot and Spyro
Team Square Enix Cloud Strife,Lara Croft and Sora
Team Sega Sonic and Selvaria Bles
Team Level-5 Jaster Rogue and Leonard
But i dought it.............
Somebody Slap me i forgot about.
Team ICO Ico and Wander
Team Odworld Abe and The Stranger
And yeah i think your right about Activition.
SUPERBOT "so Activision we would love to put Crash and Spyro in our game that's made for our loyal fans and to celebrate the playstation legacy what do you think"
