Out in November 2011, but the themes of the characters shown up until now have been released. I ripped them from the site and faded out Vergil's and Strider's (they weren't for some reason). I'm terrible with looping, so only one loop, but maybe someone else will upload a looped version.
So here's your Ultimate music fix until there's a full soundtrack. =)

Dat Marvel themes (http://www.megaupload.com/?d=MQIBPBXP)

I will update with the remaining 4 character themes once they're released.

Thankooo.
