It is way too early for most people to even hear the words Gran Turismo 6, but not for Kazunori Yamauchi who openly talked about it.
To quote from an interview with JoyStiq, available in video format below:
"How interested are you in the PlayStation Motion Controller?
Motion controller has infinite possibilities and the level of completion of the actual device is going to be very high just from the start.
I think it's going to be very important, but as for its importance in GT, I don't think it's going to have that much of a role in the series. As for the PlayStation Eye, we're probably going to try and use it in Gran Turismo, but we can't go into details of that yet.
What are your plans for Gran Turismo 5?
GT5 is a title that was pretty much remade from scratch, but because we did that, the next version is actually going to be faster - the time period it's going to be released.
But I think when GT5 comes out, we're still going to have things that are left undone, and whether we complete that in GT6, or the next version for PSP, I'm not sure yet. I've been working very hard for the last 15 years, and I think that hard work is just going to continue."
