I didn't mean to say that the DS is getting no original content, I just think they port/remake a bit too many things on it though. Those 3D remakes are still cash-in's in my eyes.
I'm sure Square don't want any console to fail, how would their multi-platform titles sell well if the PS3 were dead? I'd imagine their PS3 support will greatly increase once the PS3 hits its stride, especially in Japan (ie, after FFXIII).
Here's a thought, maybe you can look past Square Enix for a second and see all the other great RPG's coming out. I think your giving Square a bit too much praise than is really due, FFXIII is the only thing worth waiting for by them anyway.
