During a IAmA session on Reddit skateboarding legend Tony Hawk was asked if there's any chance of a fifth Pro Skater game. He replied:
"There is a CHANCE of something in the future for newer consoles. In the meanwhile, we are releasing TH Shred Sessions for mobile devices (iOS, Android, tablets) soon-ish. I'm going rogue with information at this point so I better shut up now."
Clearly a skateboard game for the new-gen consoles is something we'd like to see. Question remains whether Activision or EA will get there first.
