I see GT5 selling over GT4 numbers, but nowhere near the 15M mark. All indicators, when in comparison to what GT4 did and the circumstances around it point to that. Plus GT5 is also competing in the same conditions that GT3 had at the time GT3 released, the main difference is that there is an actual competition to the game nowadays, so that's why I don't see GT5 doing 15M. But over 10M? sure.
