If you guys run into any issues, please be sure to report them here.  Please make sure you include your system (I know, it's 360 for now, but please restate that) and how often you've seen it.  The more detail you can provide, the better.

Thanks...I'm looking there also.

System: Xbox360

Just picked Megaman, Iron Man, and Venom, against someone else that was Cyclops, Iron Man, and Iceman. Somehow our Iron Man characters glitched, appearing as Iceman and then the graphics glitched out as well for special attacks. After a few seconds, the game just froze.

System: Xbox 360

1. I have noticed sound hiccups on the main menu and the battle load screen. They are seldom on the latter.

2.(playing in widescreen) The one stage with the bridge in background has a strange black square which is visable hiding behind one of the mountains. I didn't see this square on the PS3 Demo.

This is the 360 verision.  I've only tried the demo so far, but the volume is way lower than the rest of my games.  I made sure the audio levels were all the way up, and it still is very low by comparison.  The music and voices are particularly low.  Just to make sure it wasn't my setup, I played SF2THDR right after and the volume levels were normal.  As I understand it, the demo is the full version with most everything locked out, so this should pertain to the full version as well.

Also, the 2xP and 2xK mappings were missing :P
