Siliconera has put up an interview they conducted with Ryota Niitsuma about Marvel vs Capcom 3. It has a lot of good stuff in there and is an interesting read. Here's a sample:
While Marvel vs. Capcom 2 is fun to play, it’s often criticized for being unbalanced. Marvel vs. Capcom 3 has so many permutations with assists and teams how are you going to balance Marvel vs. Capcom 3?
The team is working very hard to make sure the game is balanced. Our process for trying to balance the game is as we make each character we try to balance it within itself. Once we have all of the characters made then we go back, pair them up, and try to find all of the bugs and points where the game is not balanced.
We’re working hard because we know this is the type of game you play over and over again. The more people play it the more likely they’ll find bugs and places where the game is not balanced. The team and I are working really hard to get rid of all of these issues before you guys find them.
In the event that players find bugs or discover unbalanced parts will you release a balance patch?
First, I’ll try to make sure we don’t need to do that. If a situation did arise we’ll look into trying to patch it.
Have you thought about releasing downloadable characters like BlazBlue?
I haven’t ruled out the possibility of that. It’s something I’m interested in doing, if possible. I’m looking a lot of other games and seeing how they’re dealing with the [DLC] issue itself. Once I decide on that I’ll make a decision.
