Ironically Microsoft's consolidation of the video gaming market might have a weird positive effect here. In cases where the ownership is disputed or split between multiple entities if Microsoft acquires all of them it gets intrinsically resolved
This only helps if they acquire every possible rights-holder who could have a claim. And even then there could be revenue sharing issues that make publishing anew impractical.
Based on Microsoft's acquisition spree, that seems highly likely. Revenue sharing I think at this point is just a matter of the correct SEC disclosures for quarter-end statements
