Re: Chain of Memories was originally released as part of Kingdom Hearts II: Final Mix+ in Japan. So far as I know, it was remade from the ground up using the engine for Kingdom Hearts II. I sincerely doubt that any remakes of handheld titles for the PS3 are likely to happen before Kingdom Hearts III drops. Aside from maybe a port of Birth by Sleep, which I would regard as a long shot, it's likely not a financially viable plan.

If you don't want to track down the handheld spin-off titles, just watch the scenes from it on YouTube to get the story. You won't be missing anything from a gameplay perspective from either 358/2 Days or Re:coded anyway. Birth by Sleep, on the other hand, is very much worth playing. As is--at least from what I've heard--3D.
