Hmm, I'm actually kind of curious why the first parties haven't at least attempted annualisation to try an emulate AC and COD style success. Is it just internal resources are insufficient, is it a fear of franchise depreciation due to overexposure.
But in terms of Sony... how could they unless they massively restructure every studio? Practically every Sony studio has their own internal studio culture, ( ND's studio structure isn't cut across all Sony studios ), and all of them run their own in-house engines.
Even with significant technology sharing, it's clear that WWS are isolated from one another in terms of 'we do our own stuff, you do your own stuff.'
It'll probably do more harm than good. I could see it being worked in some fashion ( Bend as ND's franchise farm or Cambridge as GG's franchise farm ), but as a massive network of studios working on annual franchises? Super risky.
