Does this make my current processor a rare collectors' item? Should I hold on to it for five more years and then sell it for huge money?
In any case, this may just be another excercise in rebranding the same product. What is an Athlon 64 now may be a Sempron 64 in a few months, but that doesn't make the products any different.
It might make sense if AMD tried to rid itself of the "Athlon" brand, on to a Phenom/Sempron split. It's an old brand, and even though it was very successful people might remember that "Athlon has been beaten", which isn't the image one wants to have associated with a new high-end line of new product.
