Marvel is up to something mysterious – something big enough to tease in the last piece of costume DLC for Ultimate Marvel vs Capcom 3.

The alternate costume for Nova which appears in the pack can’t yet be explained.

“The truth is, I’m still not allowed to tell you what this Nova is from,” Marvel’s Chris Baker wrote on Capcom Unity

“I’ve seen it stated that this new look for Nova is based on his new look in the comics (specifically, MARVEL POINT ONE). Close! But wrong. You’ll find out soon, I’m told, but I’m sworn to secrecy until then.”

The secrecy surrounding the new costume suggests a link to an unannounced project, or a surprise appearance in an unreleased piece of Marvel media.

Joystiq notes Marvel has a major announce planned for SXSW.
