Probably not!
The thing about THQ is that they like to operate away from the WWE. They have done it for years and the WWE seem pretty happy with the way that that is working out for them. No way in Hell would the WWE let THQ put out a game that wasnt remotely entertaining and to do that, they need to make it push the envelope somewhat. Not so much that they are going to get slated by the people who will scrutinise everything they do. But they do need to give us enough material that we do not feel let down by what we buy.
The contract between the WWE and THQ is a long-standing one and I think that whilst the angles and talk on the SvR games have been toned down somewhat, they are far from PG in many respects and I dont expect that to change any time soon. The thing is, WWE PG hase been around for a good couple of years now and the games have not suffered because of that. In fact, I would probably say that last years effort was probably one of the better games. If anything, it forces THQ to come up with new ideas instead of relying on gratuitous swearing and violence to put out a successful game.
