Our Hype Train is nearing the final stop for the base game, so I'm gonna look back at reasons that I support Team Real.
-It's way too elaborate if it is faked. Much more than the Rayman leak. Papagenos posted a really good article yesterday summarizing this point.

-All the characters make sense.
--Geno, Isaac, and Banjo are the fan requests, and the biggest ones not in thus far at that.
--Mach Rider would make sense as the retro rep. Also Sakurai buying the mech toy for the gun in 2016 that matches the gun Mach Rider has
--Chorus Kids were planned but scrapped in Smash 4.
--Shadow and Ken are common sense echos, Shadow in particular has been requested alot.
-The insiders all seem to butt heads in terms of what their sources say. Also, some are unreliable, some are inconsistent, and some just say things which don't make sense
All this adds up and makes me think it's real. I really hope it is, and seeing as how Sakurai's focus in many things has been focused on what the fans want, I think this roster makes alot of sense.
