"As for why Mewtwo isn't paid content from the start, releasing that character is an experiment meant to act as a foothold in content distribution; thus it's simply meant as part of the service we're providing to gamers.

...What I can say now about paid DLC is that we aren't working on anything at the moment. We've put all our efforts into making the actual game. Creating DLC would involve large additional costs and require the involvement of a lot of people.

Creating a single fighter involves a huge investment, and we've already been giving it our all and investing a lot of work in the characters currently available in the game, and I think it's an incredible package in terms of the sheer amount of content in the game. But it might be that people may not understand and may think that I am not offering enough just by looking at DLC itself.
