There was serious talk at one point a long time ago of VII, VIII and IX all being remade (to what degree is questionable - it could just have been a port of all three on one DVD or something) for the PS2, as well as V and VI being remade for the DS in the same style as IV's DS remake, but anything else is just typical internet rumours.
