Mario Kart is going to do close to ten million, possibly even more than that.
Gran Turismo used to do 10M+, but that was on the PS2, which was a whole different beast to the PS3.
I continue to believe GT, GTA, and a few other franchises did extremely well on the previous Playstations due to the hordes of casuals that loved them to bits, and that the sales of both will take an extremely deep dive on the "casual-hater". This theory has yet to be tested, but if I'm right GT5 will be lucky to hit 4 million.
Of course I could be wrong, and the two games might end up neck-to-neck. I think the sales of GTA4 will be a good indicator of things to come.
