Remember the F-35 is supposed to replace all the USMC hornets as well as the harriers. Any fighter track should in theory position you to *eventually* transition to F-35. Even if they end up keeping some hornets, or acquiering super-hornets (to offset F-35 costs) I imagine there would be plenty of opportunity for those who want to make the jump.

But like USMCFLYR said...it could take a while longer than expected
