I said it before, The ones who got burnt this generation were the ones who came into it thinking it was going be a one console show again(PS3). The shrinking Home console market, while booming handheld(With two completely different systems), Worldwide audience, Mutliplatform engines between the two HD systems(PC also), Digital distribution, Casual gaming, and two different levels of Home console(Wii vs HD systems). Allot of these changes, Japanese developers weren't ready for...probably even though was possible. While Westerns ones were in a bit better shape for it. Best example is probably SCEA compared to SCEJ.
The 2nd thing is a bit of a perception issue. Handhelds vs Home Consoles. The Japanese support on DS has been fantastic. Yet, so many people refuse to acknowledge it. Instead when SMT:SJ was announed, It got allot of," Well I wanted an HD SMT instead". I see it in the Persona PSP's threads also. Allot of this..."Well hopefully 5 is on PS3". There is this incline this generation that if it is not on 360 or PS3, It's lesser. Yet DS/PSP is were the Japanese support has been the strongest and best. I would not be surprised if Inafune is another one who thinks of 360/PS3 as the main course, while Handhelds has a side dish.
