Well, we knew Marvel TV was involved with the production of this and Hellfire
Or... money
I mean they get a revenue source without having to do much leg work.
Similar to their Sony/Spider-man deal
Gonna have to disagree with you.
They already get plenty of revenue source right now from FOX without lifting a finger from their XMen/FF movies. They are making bank on their movies/TV shows/Merchandising. They don't need an extra revenue stream when they could get rights to their characters or put an expiry date so they could eventually get them back. It would be an extremely short term strategy to give up the rights to a TV show to FOX for just a licensing fee. FOX owns movie rights to some of Marvel properties that they know they could make plenty of money on and would like them back.
Marvel offered FOX the option to extend the film rights to daredevil in exchange for FF/Galactus/Silver Surfer/Skrulls/Dr.Doom or probably a combination of the above. FOX declined. I think it's pretty obvious what Marvel wants and probably asked for
Marvel/Sony's deal is completely different. Disney bought the merchandising rights to Spidey in exchange for not getting a share of the movies in 2011. It's not like Marvel gave sony the rights to make ironman tv for royalty fees. They are getting Spidey showing up on MCU in exchange for creative ideas and possibly character cross overs into the next spiderman.
I just 100% disagree with you that Marvel/Disney would okay, not one, but two XMen TV rights to Fox for cash when Fox holds some very important Marvel movie rights. That would be extremely short term and, IMHO, stupid.
