Honestly, I feel as if by this point in time, Sakurai is going to NEED to NOT use international recognition as a factor. It might end up hurting Smash in the long run, limiting the character selection and all.
I mean, you all wouldn't believe how disappointed I was to hear his words on how we shouldn't expect the likes of characters like Donbe (and I guess Hikari, to an extent) due to the international recognition issue. Heck, I was even more saddened to hear that this was what more or less stiffed Ayumi and Taka out of playable spots on the roster.
Which still goes to show the F.E. bias was a little TOO strong even then. Heck, Marth was even planned for the FIRST Smash game. That HAS to tell you something.
Look, I know the likes of Ayumi and Takamaru didn't exactly have many things under their belt like F.E., but the bias here is REALLY starting to hurt...
I mean, look at...Panel de Pon (a.k.a Puzzle League). That was technically an on-going series, and there's been no word of Lip even being considered for Smash, let alone make a physical appearance in the series.
