I really, really hope so. He comes from one of the most critically acclaimed games on the Playstation 3--Journey is one of those games that even the PC Elitists go crazy over. He is immediately recognizable.
His simple gameplay allows enough flexibility for Superbot to come up with a moveset. Gliding, calling, riding sand, summoning scarf-creatures...just a few ideas.
If anything I also hope we see a Journey stage.
