Yes, RPG Magazine reports that Square Enix is currently considering bringing back Super Mario RPG (originally released on the Super Nintendo and the pretense to Paper Mario) to the Nintendo DS. It will include, appearely, more characters from the Final Fantasy universe.
The second whisper helping to keep the rumour mill churning is that Ogre Battle will be making a comeback on the Nintendo Wii and that Yasumi Matsuno, former games director at Square and massively respected games designer, will be involved.
Last, but by no means least, is chatter that Camelot will be resurrecting the Golden Sun series on the Nintendo Wii. The brilliant RPG was last seen on the Game Boy Advance in 2003. Word has it that battling will take place mostly via the Nunchuck controller.

Even if these are just rumours, I hope there's some substance to them.
