Two more movies after this!

Not much other than that but it's safe to assume that aside from Vin Diesel returning, we'd also expect usual cast members like Michelle Rodriguez, Ludacris, Tyrese Gibson, Jordana Brewster and Nathalie Emmanuel to be back. I'd also expect both Sung Kang and Lucas Black, both of whom returning for F9 to be returning for these two instalments. Let's hope that Dwayne Johnson and Jason Statham will appear along other cast member who are missing out on 9 like Scott Eastwood, Kurt Russell, Luke Evans and Vanessa Kirby. Hopefully both Eiza Gonzales Ryan Reynolds' "Hobbs & Shaw" characters show up as well. I'd say Cipher (Charlize Theron) and Jakob (John Cena) will both make it out of F9 alive.
My predictions for the next two:
Ten will be a "Civil War" type of movie with Dom's crew pitted against Hobbs' team (the Shaw siblings, Reynolds,ect) and they could resolves the whole Han/Shaw thing.
Eleven will be their "Endgame" where the two teams go after Cipher (or who ever the threat is, Eteon?).
That's about it.
