Sony's PlayStation All Stars Battle Royale continues to build major anticipation with its forthcoming November launch.  And while we did just get three new fighters that add a lot to the picture – Medievil's Sir Dan, Heavenly Sword's Nariko and Metal Gear Rising Revengeance's Raiden – we may not have seen the last of the character reveals.

Some artwork that has popped up online indicate that Kat, the main gravity-shifting heroine from the PS Vita release Gravity Rush, could be appearing as a playable character in the cast.  In addition, some early images indicate that a stage based on the hit PSP series LocoRoco could also be introduced in the weeks ahead.

Sadly, Sony Santa Monica isn't saying anything – not yet, anyway – so we merely have to accept this as rumor for now.  Still, Kat would be a great addition…along with Robbit from Jumping Flash! and Crash Bandicoot.  But that's just our two cents…

Look for PlayStation All Stars Battle Royale on PS Vita and PlayStation 3 this November!
