I blame Sony and Activision not Superbot. Sony has to make a deal with Activision or other 3rd party developers, while Superbot just chooses from the choices they are given.
I'm sure they wanted them, but SB or Sony clearly didn't care about them as much as they should have imo.
Playstation All-Stars Battle Royale Accomplishments:

1st Ever 2v2 Player to Black Belt level 300

For some reason I just can't see them in the game. It'd be so cool if Spyro was in the game, that was my favorite game on the ps1. Maybe he'll be in playstation all-stars battle royale 2 or something. ^_^
