About half of that list is Western-developed and the other half is Eastern, so it's well-balanced in a way that may never happen again due to the what platforms the West and East supports. Japan is heavily portable-focused, so many of those publishers favor the handhelds over consoles while the West is console-focused despite the 3DS doing well there. Sports and racing games used to be all over the PSP, but not the DS, and the Vita not doing gangbusters out of the gate seems to have killed that avenue for Western publishers.
Sucks for me, too (I know, it's always about me!), because I like Japanese games, Japanese games are on the portables, and portables are kind of de-emphasized in the West (despite the success of the 3DS).
