Variety is reporting that new Fox will be ready logistically to close the deal on January 1st 2019.
This is referring only to the state of readiness of the new Fox entity but they expect the full ratification not to happen till the first quarter or at most the second quarter of 2019. This in effect means that the longest projected time for all this to be done and dusted at the moment is middle of 2019.
This feeds into my belief that the reason for Fox pushing Dark Phoenix out till June 2018 was due to expectations that by that time Disney will own the properties and they can then decide what to do with that movie and with coming New Mutants movie.
The bright new future of the MCU is closer by the minute, Avengers vs X-Men anyone?
