Difference between Fox and MCU? They (MCU) had a CLEAR road map and plan from the end of Iron Man. The only surprises in their schedule came with the success of Guardians of Galaxy and acquisition of Spiderman (the productions of GotG sequel and plans for Spidey pushed back everything in phase 3 and even moved Captain Marvel to phase 4) and the axing of The Inhumans. Mind you, all these changes came like 10+ movies into their shared cinematic universe project. So no big deal, unlike Fox whom is pushing a single movie every two+ years, and all of them sans Deadpool (barely part of the shared universe) are sequels of the last, so not "shared".
