The xbox 360 demo isn't bad, although it is only 1 minute quarters. From people who I have talked to who actually have the game, they say it's much more polished than the demo that was on XBL at least for the 360.
I have mine on pre-order.
With only 8 Divas, and being on both Raw and SD. I think it'll be shorter then that.
Unless they're still only voting off one every week.
That's still too long. I still can't believe they are even doing this again for what? The 3rd year?
