No, PS4 will change nothing and Sony itself is partly to blame for this. Sony is a Japanese company and they treat their own country as not important, they releas the ps 4 at the very end there. This tells all about you have to know about how Sony views japanese market.
Japanese customers and developers are focused on Smartphone and Handheld gaming and Sony does their best to change nothing about this.
Glad you brought this up, I was curious as to why Sony released the PS4 last in Japan, they always released their new gaming consoles in Japan first what changed?
