CALLED IT!

And by it I of course mean Hawkeye showing up. I now give up all my humility when proved wrong with the initial release based entirely on my prediction of Hawkeye. Other characters I predicted would show up: Frank West, Firebrand, Strider Hiryu. Other Characters that are going to be in it: Ghost Rider, Iron Fist, Rocket Raccoon, Dr. Strange, and Nova for Marvel. Which Nova I don't know, but it's probably going to be the Human Torch's Girl friend. For Capcom: Phoenix Wright, Nemesis and Vergil of DMC. Whether or not there will be even more DLC with characters like Doctor Octopus, M. Bison/Vega, Megaman X, or Cyclops has yet to be revealed. But you just know that people will be clamoring for it. Now if only they transfer over your old DLC, I will be a happy gamer. And of course keep coming out with more costumes.

EDIT: Turns out that it is the Nova Corps version of Nova, not the Sentry of Galactus that I predicted. Admittedly that would have been pretty interesting for the final boss fight.
