So I actually went back to looking at the Dante articles, and I feel it's best to clarify.
First, Mr. Itsuno is interviewed and the article for said interview is published on February 7th. It can be found
here. In the article, he says that Dante should be on Nintendo consoles first before being in Smash. He says, "Get on it!" around the "port manager" who happens to be at the interview. So this now happens to be over a year ago.
Next, on May 7th, Devil May Cry Switch port is
announced officially. This means there's a timeline of 3 months where the game is announced for Switch. Obviously negotiations are a thing, as is development. Granted, it's a port so much of the game is already set to start on.
I
do think the whole thing is interesting. Doesn't confirm Dante at all, but the thing of it is...the context of those comments was Dante being in Smash. That in itself is pretty crazy.
