I never said Stafy was unlikely anyways. I was just pointing out that, instead of opting for such characters in Melee, they went for the more human-like and "serious" ones, because they knew most of the people who were waiting to play that game were older than 10
(not to sound mean or anything)
Brawl's hype is stemming almost entirely from this same demographic, 16-30 year old males. So of course they're going to throw in people like SNAKE, ZERO SUIT SAMUS, and PIT. It makes for a great game all around for everybody, sure, but who's going to appreciate it more? A kid who just found out who Snake was, or the guy who played Metal Gear Solid religiously when he was in high school 8 years ago?
