"The PS Vita is a very powerful portable system," Yoshida said, "but not quite as powerful as PS3. As you can tell looking at GT6, it really is using PS3 to a very high level. So it’s going to be really hard to move GT6 onto PS Vita."
He went on, saying that "in terms of PS Vita support, I don't expect the whole game to be able to run on PS Vita. So there's no clear plans right now that we can talk about."
Polyphony Digital president Kazunori Yamauchi previously confirmed that the studio has a vision for a PS4 edition of the game "in mind for the future". While no official plans have been revealed for a next-generation version, Yoshida described the transition as "natural" once the studio has come to grips with the PS4 hardware.
Gran Turismo 6 is scheduled to launch on the PlayStation 3 this December.
