Paramount's in a lot of financial trouble right now. They need AQP2 to be a theatrical success, which is why it got moved to late April and not streaming like pretty much everything else on their slate save for Top Gun.I suspect A Quiet Place II is next to drop. I believe there were rumors about it before, but now that Mulan has made the move I suspect A Quiet Place II to do the same. Either Disney will drop something big in Hulu, or Netflix and Amazon are going to acquire something we'll see what film it is.
There were rumors a week or two ago that Disney is considering putting Soul on Disney+, so I feel like that's the likeliest candidate to move next. However, that's still 3 and a half months away. Theaters could be open by then.
