Anyway from what I recall, both Mac and Ridley are/were "noted" in Japan for their overseas popularity. Ridley isn't unknown at all, considering even with diminished popularity he still managed to warrant the aforementioned (2nd) most mentions by Sakurai in that pre-Brawl poll thingy/two boss fights and trophies in Brawl. Metroid does have less popularity over there, but not to the extent people imagine (Prime sold less because the Japanese aren't as big on First Person Shooters/Adventures as we are here, not to mention the whole deal with handheld gaming being preferred to home consoles). Basically they view him how we view most additional reps to older series (as in they would be cool additions, but aren't necessary). Granted this is just assumption and speculation, but I'm almost positive they'd be just as hyped as we would to see him anyway. Just not before the likes of Mewtwo, Roy, Dixie/K. Rool, etc..
