Weirdly enough, Digimon Story was on the DS line, while Digimon World was on PSP.
DWorld is now on 3DS, while DStory is on Vita. I haven't played any Digimon Story games, so I don't know what to expect.
Though it looks like the game happens on the "real" world, so I'm actually liking the setting.
Edit:
So I guess... only one game I'm looking forward to hasn't given a new info lately:
KanColle Kai (Kantai Collection).
I hope it's lewder... I mean it plays good and have all the voicework from the original game.
