Supposedly,
this guy is in charge of making the list of people to invite and he's part of NoA. He's been in a few of the Directs before (usually when they have to announce some localizations? I think?) Anyway, if you check who he's following you can see he's following
tons of Smashers from Mango to Android (Armada's younger brother) to Kounotori (Japanese Falco player) to progducto to TKBreezy to ChuDat to even Shroomed and S2J (there's more he's following obviously, like he IS following Armada).
Now obviously that's not an indication of
who will be invited exactly, in the end, but it's a good sign that because he's the one making the list of invitees we may see some of the people he's following on it. And also, him following prog and D1 gives good hope that they
might be the commentators. Again, it's at least a sign that someone in NoA seems to follow the Smash competitive community.
I really hope it turns out OK, anyway. I really doubt Nintendo would use some small Japanese tournament to decide who gets invited to this lol.
Although weirdly he's not following PPMD or Mew2King. But like I said, who he's following wouldn't necessarily be a 100% indicator of who's on the list lol.
