I agree, dunno what the logic is behind the Mewtwo pessimism, but it doesn't seem that widespread. It's just the fact Pokemon has a new character and it's
not Mewtwo, but it's inarguable that we have plenty of space for another one or two. Jigglypuff is almost certainly going to return, but Mewtwo isn't much worse off than her - he's got far more popularity now than he did for Brawl plus he's not a new character, so putting him in won't be so costly for development time either.
I'd be shocked if Sakurai didn't go for Mewtwo, to be honest - you add back an old veteran, sure you'd probably have to spice it up, but not to the point that his old model/animations don't help. The return feedback and hype is so worth the effort.
