Streakeagle, I'm not sure. When these fighters were designed in the nineties of a now forelorn millennium, indeed the F-22 was the supposed F-15 replacement and the F-35 the F-16 follow-on.
But we are now 2011 and the game has played out quite differently. Honestly, the F-22 is at its best while grounded: saving taxpayers' money at an incredible rate. Since no one really came to play its game, it is in search of a true mission. What is worse: it lacks true network integration with other assets, has no optical systems (often required for ROE) and proves very hard and costly to upgrade. An F-16 MLU can carry AIM-9X + JHMCS, to name a few things. The F-22 carries yesterdays missiles.
The F-35 is no longer the sustainable, affordable fighter it was meant to be either. Instead, it has become the technological flagship of the day, including technology on average 10 to 15 years more recent that F-22. And what is even better, in the F-35 you will actually be at the front row in any future conflict, while the F-22 has been sidelined during 3 wars already.
My guess is the top pilots will want a seat in the hottest fighter in town, the F-35.
