So, the Russo's said that they didn't have to worry about setting up WV and give some sense of closure to the Infinity saga. Which is interesting considering Paul Bettany said that he was supposed to have an end credits sequence that was cut. And I'm sure many were looking for an end credits scene while watching that never came. And I'm sure there were plenty of viewers including myself who thought "Great, what comes next?" I'm sure they're being coy. If the Russo's weren't aware of Phase 4 going into EG, they're fibbing a bit.
