Venom is now a financial success, Tom Holland signed for 6 films, 5 with Marvel Studios.
That means he will still owe Sony a film, meanwhile Venom (financially speaking) is a successful launch pad for Sony's Spider-Verse.
Why would they want to continue to share Spidey with MS if they could get Tom Holland to re-sign for another 3-6 films.... ?
This is how I see it going, thoughts?
