Yeah, hi. That's me and my work.
I wasn't aware of the Mother 3 delay or that Lucario debuted in the movie. Thanks for that,

Anyway, I used this data mainly to help see what kind of range we'd be looking at for characters. And what I found was that, in all likeliness, newcomers for Smash Switch would hail from Wii U / late 3DS, so right around August 2012, up to probably sometime in mid-2016 (with exceptions for Pokemon, of course). Originally I had extended it to just before Switch's launch, but now that you mention Mother 3's delay, it makes far more sense to have BotW content considering the numerous delays.
I made a roster prediction based on that, but I'll probably be changing it soon due to a bunch of other factors.
What else could it have been?
