I haven't made up my mind yet but I'm just dying to see something lol. The couple of teases they put out looked good already so just go for it. They are wishy washy with their marketing decisions lately, didn't show live at all!
I just think a game with no competition in its market you could give us a taste. They used to show like what they were doing behind the scenes foot planting and stuff like that with madden and live a few years back using generic models, stuff like that could be cool to showcase grapple and submission systems, and build up to the games release.
