The Last Jedi can't really make below $1.4B
TFA made 1150 OS, TLJ won't suddenly drop to like 500, this isn't Rogue One (even with Exchange rate drops)
It also won't drop to Rogue One levels domestically. Everyone wants to know what happens next, especially with Luke around
Floor to me is $650M DOM and $750M OS
My prediction - $230M OW x 3.50 = $800M DOM + $900M OS for $1.7B WW
