This honestly feels like the Jonesy situation from December. Everyone thought that Jonesy was hinted at by Geoff Keighley based on a Fortnite Tweet he made for TGA 2020, and as such, everyone thought he was coming. But of course, this ended up being completely false, as Sephiroth entered the fray instead. Nobody is allowed to give any hints as to who is coming, regardless of whether or not someone comments on it. If they did, that would be an NDA violation.
Speaking of Geoff Keighley, he also tweeted "Woah!" in a reply to a Tweet, which some people took as a hint to Crash Bandicoot, among other Crash related stuff. Once again, this didn't end up being the case.
