I doubt very much he will get removed. He's obviously a part of story mode, and less than 2 months from release I don't think they'd have time to redo it.
Besides, Stone Cold has been guilty of spousal abuse in the past, and he's still in the game. Superfly Snuka killed a woman in a hotel room (allegedly) and he's in. Luger was responsible for Miss Elizabeth's drug overdose (allegedly) and he was in the last one. I'm not defending Shamrock in any way, but if you removed very wrestler who has been guilty of heinous acts from every wrestling game, you'd pretty much end up with just CAWs!
I'm not climbing to the top of the mountain. I am the damn mountain!
