For the millionth last time, the 7D is a different line of APS-C and is not the Canon successor to the 50D. The 7D does indeed allow you to pull some shots that you otherwise would not have been able to with the 50D, depending on what you shoot. Just from the improved AI Servo II (either taken from or developed in conjunction with the 1DIV) alone...
Then again, depending on what you shoot, the 7D may just not do anything more for you than a 50D or 40D, however, the features are substantive over those two and the featureset may be enough to warrant a switch to the 7D.
Hahaha Teamspeed, lighten TF up! I was jokingly taking the P-eye-S-S out of Canon's marketing bumph, and relating it to artyman's perfectly valid comment about skipping the odd generation of EOS body!
YES, WE ALL KNOW THE 7D IS NOT "MEANT" TO BE THE SUCCESSOR TO THE 50D, COZ THE CANON MARKETING DEPARTMENT SAY SO, AND THEY MUST BE RIGHT!!!!! Sheesh!!! 
lol
Your second para makes some good points, tho
