BVG = Buena Vista Games. I think it's just the new name of Disney Interactive.
I also predicted that it would be E10+. It definitely has too much "questionable" content to be E, and there's definitely not enough to be T.
Anyway, yeah, this was posted a while back, but it only came from a single source so we couldn't really back it up. Now that it's come from 2 different places, I think that pretty much confirms that it's real.
