Neanderthal, dont bring that guy onto this thread!
Super Smash Fan, I still have to disagree on the whole Mega Man thing because of what Sakurai has said. During interviews, he's stated that he can't start adding 3rd parties willy nilly because it ruins what the essence of what Smash is, a Nintendo brawler. Nintendo franchises. I 1/2 agree with Smashchu on his 3rd party argument. I think realistically, there will be none added, however, I do not think that Snake or Sonic will be cut. Cuts are very unfavorable among the Smash community, but I think Sakurai will stick to his guns on not being able to throw in too many 3rd parties, or even adding any at all. Yes you can say, "Well Snake & Sonic made it, so Mega Man should because he's so popular and could fit" but that opens the flood gates. Snake's inclusion undoubtedly opened the door for Sonic's last minute addition. I fear adding Mega Man will only do what Snake did for Sonic, and make it easier for 3rd parties to get in, like the "well if I did it for some 3rd parties, I have to add all the big ones to be fair" kinda thing.
However I do recognize that if one were to make it, Mega Man is probably the top with Lloyd Irving (can't discredit his huge Japanese popularity, look at FE).
