11 was bad because it just plain sucked. If anything, they'll just add more bs options that do absolutely nothing for the normal user, or they'll come out with some "master codec" just to hype up 11....
But in the end, if they don't get some newer and updated visuals in there for music, then Microsoft will have failed me again. Right now, M$ needs something flashy to show off their new line of products. Unless they do that, I will never switch from winamp. Milkdrop > any other interactive music visuals.
