If they go this route then the FF movie should be pushed back. Near the end of the Phase 4 thread I posted a listing of all current properties Marvel Studio's is juggling and another new IP spunoff from the FF franchise I think would be great but just maybe not much room at the moment.
Still, if they make this I want films connected to this in quick succession instead of narratively going elsewhere for 5+ years between installments.
Nova was supposedly supposed to take place of Gaurdians of the Galaxy slot then later Annihalation seemed be in the backdrop then earlier this week he's rumored to take the Spider-Man slot now I think Silver Surfer could very well do that instead. Even so, Marvel just may go back to making a deal with Sony at some point too. There's almost too much at the moment. I think Marvel should probably keep things in development but maybe not trip over their own feet trying to release new IP's leaving too many dangling threads with other movies.
