Hmm.
I’ll just assume fake, then, and that Geno and Doomguy don’t come with these hats if they’re in, or at least the hats don’t look/aren’t quite the same as these. Sabi’s source did just say “most likely,” though, so still not a Grinch situation and it implies it could still be real; his sources aren’t devs either, and might not know playtesters, but idk. I like these hats so I still hope it’s real, but at least we seem to be most-likely getting Geno and Doomguy anyway.
I still don’t understand Sabi’s tease on twitter, either. Of course, he could just be trying to hide Nintendo stuff, but most of the discussion going on was Smash so it was just weird to tease stuff like that if he had nothing on Smash.
