Does make me curious how the other follow-ups to Disney's original hits from the 2010s will do!
Pretty much everyone expects a substantial increase for Moana 2. A similar bump to the one I02 is getting can get it easily past $600m OS.
Zootopia 2 has to deal with the fact that the first broke out to $236m in China, which is just not gonna be repeated with Part 2. But it was big in Korea, which has grown massively since. The growth of Mexico and the success of animation there recently may also boost that one. I think even matching the original, with a potentially big dip in China, will be a huge win.
