Sit down. He's joking. Unless he's magic.
OP:
If GT6 was on the shelves, even next week, I'll buy it - even though I've still not completed GT5 100%.
In fact I sometimes go back and play GT4 and 3, because I've not completed those 100%, either.
What if there was no GT6?
What if the slip about 'GT6 coming to PS3' was intentional - a marketing ploy?
At this point we don't know a lot - that's for sure. But if GT6 was made for PS3 - sure, I'll buy it - I wouldn't skip it. There are many reasons for buying a game - I have a few.
If it came along a year after the PS4 launch - maybe even better (obviously? PS3s getting old, next gen game, etc, etc) but until then Kaz is going to have to feed us DLCs every which way but loose to keep hardcore GT5 fans from climbing the walls. Can he do it?
We have to remember, too, that many players have heavily invested in this game. How easy is it going to be to just let it go and start on the blank slate that (possibly) would be GT6? Would any data be transferable?
