Thats an entirely different topic than the point I was questioning but I'll address it. One, that's an even bigger risk for not much reward. Two, it also assumes that there's multiple studios worth of AAA capable talent out there that is afit for Sony. Three, Sony shouldnt be singled out for that when all three platform holders have arent expanding their first party studios much outside of MS who had several reasons why they were forced to do so.They can gather talent, open new studios or even acquire them, they can greenlight a good looking pitch and actually try to fund and market it, if they really wanted or cared.
They're just not comfortable with anything that isn't a big, cinematic western action game at this point, and they only care about the US market.
Also Nintendo shows that being an hardware and software developer that isn't costantly ashamed of having an explicit and blatant Japanese identity can grant you a wide global appeal just fine.
The bottom line is no one can accuse Sony of not rewarding their japanese studios with more autonomy and wealth after they've met a certain bar of success. They were willing to do that with studios that weren't owned by them (KojiPro).
