Look, I have no basis, what so ever...but my gut tells me, Marvel will assist Sony with their lofty ambitions, in some capacity, be it small or major....from laying the foundation of a story, for Sony's writers to proceed from there, to actually help produce these films. Just a gut feeling...let me explain why, so hear me out:
Marvel cares dearly about Spiderman. Disney cares dearly about Spiderman's marketability...especially to 12yr old & younger; but, to everyone...young or old, adults or teens....all.
They, Marvel and Disney(MaD) know that Sony is going to do whatever the hell they want, in trying to build their universe & cash in on their prize possession, during this huge profitable era, we call comics2films.
MaD do not want Sony to go down the path, of ruining one of the three biggest comic book characters today, that they have re-established....2nd only to Batman(not for long thanks to Afflack) & ahead of Superman; when, their name & the MCU hinges(shared agreement) on Sony's proven track record...with what has been already hugely successful, without, the biggest known commodity in the Marvel Comics....Spidey.
Again....after MaD just re-established a path for that commodity(Spidey) to take its rightful place at the top...at a time when MaD have "NO" sole control of over this prize property.
So I think Feige is swallowing his pride(& we saw that in that interview) and will do, maybe, the bare minimum, so as to not tie MaD & the MCU hands, to Sony if the ship sink, but just enough to keep the Spiderman Universe as a whole, viable for yrs to come & reap the rewards.
Business is business...and there is a lot of money at stake. Not just films; but, distribution, syndication, marketing, toys, naming rights & tie-ins, clothing & apparel, etc. Marvel, ESPECIALLY DISNEY, is not going to leave that money on the table to wither.
I'm just saying....MaD can't get the rights back w/o paying a hefty price; so, they have to play ball or else watch what they have re-establish be ruin....and now that they(MaD) have gotten a taste of how big Spidey can be, under their supervision, with minimum creative control...are not going to let that go for not.
Now, a transition is about to occur in a few yrs, after IW's2 is done & replacement of beloved actors occur...Holland/Spidey is going to be at the forefront, leading the way, for lack of a better term, Phase Four. I'm sure Sony is aware of that.
Who will lead the way when that come...the very character, they don't have full control of...whom already is beloved & is appointed the Peter Parker we all have finally been waiting for.
You think with so much as previously stated, at stake, MaD are going sit idly by & let Sony slowly & methodically ruin that...with all of these spinoffs, that is stated, will tie Holland's Spidey to...the possible new face of Marvel's Phase 4 going forward?*
The shared agreement is just as much a curse for Marvel as it is a welcoming homecoming. Simply because they don't have sole control over a character that's prime to be the face of the MCU, after replacements. For Sony, It's about right now & beyond. Sony is formulating an extention right now for Holland pass his three film contract.
Disney is shrewd; but, they have to look towards 2020 with a shared character that will affect everything, in some fashion...big or small, after the process of replacing beloved actors.
I think Sony is just using these propose spinoffs...building toward the Six; which we have know for a while now, something, very much like Venom, they been wanting to do for a long time.
Think about it...doing spinoffs of these villains, by the time the group is form to go after Spidey, the villains background, history, persona...all of that, would be readily established & the GA(general audience) will already be familiar with these characters & what they bring to the table. Not bogging down solo, stand alone, Spidey films, with tons of character development, motives, & plots.
This is what I see going on in Sony's mind & think MaD will get on board at some form or fashion. Whether we agree or not...it's not a bad idea imo...I just pray to God, MaD has some hand in this....because Sony needs help. That's part of the reason the shared agreement is in place, in the 1st place.
