I feel we need to change the perspective when it comes to japanese gamesales. It´s clear that this generations dominating system in Japan is DS. It doesn´t matter if it is a portable. It still is the dominating system in Japan.
Evidence on this is also the huge amount of titles that traditionally went to homeconsoles from japanese developers that now are on the DS (and also PSP). Dragon Quest which always finds a home on the leading system (NES,SNES,PS1,PS2) is now on DS, that says a lot.
