Gran Turismo will not sell consoles, though.
Look at GT5P, sold 220k first month NPD, never charted in the NPD top ten again. Yet supposedly sold 4.5 milion copies.
GT games sell, but they sell as bundles, $20 greatest hits, etc.
FPS games are what really drive console loyalty far more than any other genre.
I think that this year Microsoft's lineup is better than Sony's.
