I am being a bit optimistic on JW3 as pre-sales are very good for the film. Could go a bit lower and considering the numbers were higher due to PS, Deadline going high make sense.
I just realised that Endgame had bigger drop last weekend in Canada than US. Of what I noticed, Canada has better legs than US. Reason IMO being Ryan Reynolds in Pikachu.
At this moment, Avatar ain't locked. I am seeing a probable finish of $2.775 Billion and that can go lower as I am being optimistic a bit.
However, all it needs is one weekend to correct the course. So let's hope this is that weekend and we have sub 50% drop this weekend internationally and Domestically.
The very best reasoning I would give is EG have better Saturday bumps than IW so far and IW bumped 75% so I won't be surprised with that.
Even 2019 on whole has big Saturday bumps.
