Very informative Chris O'Leary article:
http://www.chrisoleary.com/projects/Bas ... sburg.html. He predicted this in June 08 from his arm action and says if Strasburg doesn't change his technique he'll look great for a couple years after the TJ, but then will destroy his shoulder and likely be done. To have a long career he needs to change his technique, slow the velocity, and not throw the slider.
Either way, bad day for baseball
