Sadly, you might well be right. Ideally, a new CEO would be a Westerner or someone with extensive recent experience in a Western market, but I don't expect either to happen.
But it's beyond clear at this point that Iwata and the rest of NCL's current management have no coherent vision for how to keep Nintendo relevant in an increasingly Internet-connected, increasingly smartphone/tablet-driven, decreasingly Japan-centric market, and there's next to no chance of their corporate culture changing without a major change in management.
Every decision that went into designing, (not) supporting, and launching Vita was made while Hirai was in charge at SCE.
Not to say that PS4 will have anything close to the same problems, but let's not pretend that Hirai's track record is unblemished.
