Also, IO had Tuesday previews of $600,000 for the Fan Event screening according to deadline. http://deadline.com/2015/06/jurassic-world-inside-out-weekend-box-office-dope-1201448898/
It's true Friday was at $30.06M.
IO will get to $350M for sure if it gets $13M this weekend. $340M? I don't think it will go that low. More like $350-360M range especially if your prediction is accurate or is higher.
Even though Shaun and the Sheep and Underdogs are animated films coming out in August, they won't even open more than $15M combined. In other words, they will not hurt Minions and IO at all.
