He's probably already including Rogue One in that
Ya. Zootopia won't be in the domestic top 5.
Boxoffice.com still has Jason Bourne opening at $65M next weekend (and hitting $195M total). That seems a bit high to me.
Bourne, Pete's Dragon, and Suicide Squad are the only unreleased films with a realistic shot at the summer top 10. Personally, I don't think that Pete's Dragon will make the $125M+ cut off. As such, here's what a rough look at what will end up being this year's list:
1) Finding Dory
2) Captain America: Civil War
3-4) Secret Life of Pets and Suicide Squad
5-7) Star Trek Beyond, X-Men Apocalypse, and Jason Bourne? (Beyond will beat Apocalypse unless it drops hard this weekend. Bourne is a wild card)
8-10) Ghostbusters, Tarzan, and Central Intelligence. (Maybe replace one of those with Pete's Dragon if it does well. Tarzan will probably beat CI. Too early to say more)
