Via November's Game Informer issue in an interview with him.
When asked what he would do if Capcom actually wanted to publish Mighty No. 9:
"I would hear their terms. If they had the best terms, I would go with Capcom. There is no reason not to publish with Capcom, and I certainly don’t feel like there’s a reason that I have to publish with Capcom. Literally it would be a very cut-and-dried business negotiation. If they had the best terms, the logical businessman in me would say, “Yes, let’s go with them.”
They then asked him if he would re-skin it as a Mega Man game as a result of that:
"If Capcom came up with really great terms to make it a Mega Man game, then of course I would listen and that would be an option. But the base of this game is that we wanted to create something original. If they gave us an offer we couldn’t refuse, that would mean having to change the main character into Mega Man. On top of that, it would still have to be our IP, which is what we want. I can’t foresee that happening. We really want this to be our thing."
