I can't speak for the intention of the purchaser, but in their position I'd be looking to just unlock the teams. My impression of Square-Enix is that they've frankly just never been a company comfortable with being international, and it has shown for a very long time now. Just let the teams go produce something without the Eastern and Western design, management, marketing... heck, nearly
all the philosophies clashing and producing much less than the sum of the parts.
(Since I know how things work nowadays, I'm not saying the philosophies necessarily intrinsically clash or that they can't be reconciled by other entities, just that to my eye, Square-Enix in particular is a company with a multi-decade track record of failing to do so.)
