Does everyone realize what an utter megaton annoucement this is? Dragon Quest is THE premier RPG series in Japan. The PSP is in serious trouble there (As if it wasn't unpopular enough to begin with). This will cause a noticable surge in DS sales in Japan. Gamers who wouldn't normally bother with handhelds will do so just to play this game. This is not another DQ spin off, it's the real deal. DQ started on Nintendo and then migrated to Sony - now it's come home.
