Assuming we get even him. Ubisoft is on great terms with Sony, so I can almost guarantee a Ubi rep, but who knows if it's Rayman.
Would you rather it be rayman or an assasins creed rep (if only one was to be announced)?
The Italian rumor is that Sackboy, Big Boss, Rachet & Clank, and Rayman are the gamescom revealed fighters.
You have no idea how satisfied I would be with that, plus I would have the mentality that sir dan, spike and Nariko will still be announced, since they are in the safe zone pretty much. It's the third party reps im worried about
