Gamestop grabbed the following quote from THQ:
We haven't announced any of this yet, exactly. But it's all part of the plan leading [up] to Saint's Row 3, and all of the games connected. So if you play one, it unlocks stuff in the big game and back and forth and all that stuff.It's time for Marx0r to get excited again.
