I personally think Microsoft and Sony money hatting some of these studios would be better for them. Especially Square where management just seems to be all over the place.It's not like they're adding indepedent developers to Xbox Game Studios. This is an entire publishing arm. It's uncharted territory.
I think we'll see multiplats from them
If Sony aquired Capcom or Square Enix i'd expect them same thing from them too. They'd be indepedent bodies seperate to WWS and how that would play out in terms of exclusivity is anyone's guess.
