I've been saying there would be nothing for months, and I choose to believe that pessimism physically manifested and cancelled whatever FP5 announcement there originally was for this.
That said, Gears Tactics looks better than I thought it would. Ori and Doom look good but we knew that already. Cable/Gambit in MUA3, Maneater and NMH3 were all pleasant surprises. Untitled Beaker Game needs to be real.
Depends on when you're talking about. Smash 4 Ridley thread was incredibly tame compared to Brawl (we went through several threads and eventually got Ridley as a thread topic just flat out banned for a time). The worst Smash 4 really ever had was how heated shadowposting would get, and some drama back when we had Social Groups.
K. Rool was a bit late in gaining traction in sense that we didn't even have Diddy when Brawl speculation kicked off, and DK hadn't quite reached peak series stagnation just yet (it was pre-DKCR). They faced arguably worse elsewhere, not just this website, whereas Ridley has kinda petered off once the comments from Sakurai hit.
Both these and Banjo-Kazooie also different circumstances, but I feel every fanbase has toxicity/a bad side if you look hard enough (namely now that everything is so widespread and out there with social media). Had any of us had similar circumstances (if any of Ridley/K. Rool/Banjo weren't already in I'm sure they'd still be just as loud as they've always been), I'm sure most others would still be critical/sick of us (if they aren't already, though I find most people kinda chill out eventually after a character/fanbase they dislike gets in).
Either way it's almost always vocal minority/echo chamber stuff that gets the biggest stink compared to those of us that just remain quietly hopeful, or just stop caring about speculation/doing the same old arguments/song and dance after a while. Debating and being passionate is fine, but some of us don't want to kill each other perceived importance of fictional characters (or are just getting too old for it) nor want to be associated with any of that noise.
I will say it takes a special kind of persistent to keep up with this rollercoaster stuff for as long as Geno has. It'd be nice to see some old friends/genuine fans of the idea get pleasantly surprised, if nothing else. Holding grudges because some people ruin it for others isn't something I think is worth the effort unless you're the Mileena stans
