Man, these aren't speculations, are updates the actors do in their social media. When I say "It's confirmed", I'm saying "Is practically confirmed". In other words: "It would be a REALLY WTF if those actors didn't ended making those roles."
Fandom's "hope" does nothing to do with this. I'm talking about actor's updates. If you're blind, that's not my fault, man.
Casting started last month, and now those actors (Coincidence?) are making all this noise.
