Most RPGs have an overhead view not sidescrolling like a platformer, what difference does 3D make over 2D? Unless you prefer cinematic cutscenes over "talking artwork". Even a 3D RPG like Rune Factory has those.
Some companies like 2D such as Vanillaware and Nippon Ichi. Nothing wrong with it at all, there's far more companies that do make 3D graphics.
3D isn't the natural successor to 2D contrary to popular belief. I wouldn't say Super Mario 64 had better graphics than Prinny, just because one's in 3D and another is in 2D. I, along with alot of people, would rather have highly detailed sprites and 2D enviroments over 3D in many cases. --- ~The Devil's Marionette~ Aspect of Madness: Schizophrenia
Well Dragons Crown is a 2D sidescrolling action RPG in a way. Rayman is beautiful and I hope it gets ported to Vita. So I do hope we do still see some 2D rpgs, platformers, and the like. --- last $$: Star Fox 64 3D, Atelier Totori LE, Dark Souls LE, Persona 2 LE Playing: Dragon Quest IX, Uncharted 2
