I think there may be minor graphical improvements to GT5 from Prologue.
As for GT6, i sure as hell hope its on PS3, and doesn't fade to PS4. There seems to be 2 GT games per generation. GT1 and GT2 were on PSone, GT3 and GT4 were on PS2. GT5 and hopefully GT6 will be on PS3.
I think it would be amazing if Gran Turismo 7 was a launch title for PS4.
