The Captain Marvel repost could be more a reference to Beast and the X-Mansion showing up but I hope it means more than just that.
I've noticed Jubilee is the only 90s TAS character not even referenced so far. Beast has The Marvels ending and the rest of the cast is rumored in the leaks but Jubilee hasn't been mentioned once. And apparently the scene from the trailer of Logan and Deadpool's power walk is supposed to feature Gambit, X-23, and Dazzler who were just cut out of the trailer. So the family dynamic of Logan, Gambit, X-23, and Jubilee from the comics is now being subverted with Dazzler replacing Jubilee. Not a fan of that. I don't mind Dazzler's cameo but I don't see the point in placing her in that scene where she doesn't belong.
Deathstrike coming back didn't surprise me but I never thought Callisto would return. I hope that doesn't mean another scene with Storm getting beaten up.
The Gambit movie not including Rogue didn't bother me that much since I assumed it was covering his prior history and it would eventually lead to Rogue popping up in a future installment. Since she's not part of his origin, unlike Belladonna, that makes perfect sense to me. What doesn't make sense is having a movie with 90s themed X-Men and not featuring these two together but at this point, I'll take what scraps I can get. But especially after X-Men '97, not getting Rogue and Remy onscreen together is going to feel very anticlimactic and rather foolish in the long run.
I'm fine with just about anyone in terms of who plays the Rogue variant, although I'd rather not see any of these variants until we've said a final goodbye to the Fox cast since I imagine their screentime will be limited enough as it is. I know Keke Palmer has been a very popular fancast online. Alexandra Daddario was one about 10 years ago...I didn't realize people are still picking her as Rogue all this time later. I don't know if X-23 was a last minute decision to include (especially if she's sharing screentime with Gambit and Taylor Swift's Dazzler because I can't imagine they could easily reshoot with Taylor Swift) because from the moment Logan came out, Dafne Keen was praised. When the Fox buyout happened, besides Deadpool, the most common actor whose name was mentioned as someone fans wanted to cross over into the MCU was Dafne. So the hype for her has been there from the beginning rather than just a recent manifestation that the MCU would try to jump on.
