I very much doubt it. This will head to PC and Xbox just like Nier Automata, Hellblade etc. MS won't need to buy any companies either, Insomniac isn't bound and I'm sure Marvel and Disney had the foresight not to get tied up in an extended contract. Even if they did, Sony would let them loose out of good will as they've already gotten all they can benifet from this.
Spiderman is a Sony owned game. Like any first party title. It’s not going anywhere Sony doesn’t want it to go.
