Well I dunno if this was shared already but I just saw this
interview and then stumbled on this question:
So first of all, thank the lord the interviewer is smart enough to not add the word "smash" on the question, lol. I feel like whenever an interviewer includes that word in a question it just reduces all chances of getting an interesting answer haha.
Secondly, whatever it is, he is definitely hyping something out he wants to announce soon as possible with Ryu Hayabusa included in him. I honestly don't think he would be hyping out the rumored sigma ports that were leaked to be coming to the switch sometime this year ( if that rumor is real at all anyway…), so it's either something new or maybe he could… just maybe, be getting in some kind of crossover, be it smash or maybe other fighting game?
