A question to all... consider the following hypothetical:
Fox and Marvel studio head honchos find themselves trapped in a room as part of a 'good faith' negotiation. Secret Wars style, if you will.
Each must write a dollar amount on a piece of paper. If Fox's amount is smaller than Marvel's, everyone returns home to the status quo.
If Marvel's is greater than or equal to Fox's, Fox receives the sum they asked for plus half the difference between the two figures. Marvel receives to rights to the Fantastic Four and all associated properties. For example, if Fox's sheet reads $5 and Marvel's reads $7, then Fox goes home with $6 and Marvel gets to reboot FF into the MCU.
Now, my hypothetical question is, assuming the FF rights revert to Marvel, what is your estimate of the two dollar figures?
