If they don’t move to 4 a year, that will be the real issue.
We’ve still got to get through:
BP2, BP3
(BW2, BW3?)
CM2, CM3
(Eternals 2, Eternals 3?)
AM3?
(Thor 5, Thor 6...?)
Shang-Chi 2, Shang Chi 3
DS3
gotg3
Blade 2, Blade 3
FF1,2,3
and that’s to say nothing of the other fox properties, teamup movies, going past 3 for some of those, or the possibility of a Spider-man deal being worked out — or continuing to introduce new subframchises like Nova, Thunderbolts, Power Pack, whatnot.
We’re seeing that some of these ides can lean on D+ to see the light of day faster, but staying at just 3 a year means some of these being left by the wayside entirely or taking waaaaay to long to develop.
