I personally don't want Pac-Man, but I'm not so jaded that I can't see that the possibility is extremely high.
And, yeah, I think that Sakurai is intentionally misleading us from believing Bamco gets special treatment this game. It's why I say I state that Sakurai's statement is reverse psychology.
"Oh, hey, even though you're expecting Namco to get representation, they're not getting any special treatment."
That's not going to make a Pac-Man reveal any more surprising, since people are still expecting it. Anyway, you wondered what my logic was for Pac-Man's hypothetical lack of presence completely debunking the Sal Romano leak? Well, like we've argued the past few posts, EVERYONE expects Pac-Man. It's the safest addition on anyone's roster. The deconfirmation of Shulk and Chorus Men is enough to debunk the leak, but the SAFEST PICK IN THE HISTORY OF SAFEST PICKS getting deconfirmed? You can't start throwing around the excuse that 'OH WELL DEVELOPMENT IS AN EVER CHANGING LANDSCAPE' and 'OH, HIS LEAKER HAD ACCESS TO OLD INFORMATION' anymore. Pac-Man would've been solidified pretty much the moment they'd said 'Well, I'm sure we can squeeze in a Namco rep since you guys are being nice enough to help us out.'.
Which, honestly, regardless of what Sakurai says, they'd have most definitely lined that up years ago when developing the roster.
So, there's my logic.
tl;dr: Pac-Man's hypothetical deconfirmation 100% debunks the Sal Romano leak by debunking the safest pick of the leak.
