Not really, the high end enthusiast parts would still be there. This would just cut out the mid and low end parts from overclocking. The parts that have the most to gain. I'd imagine they're making processors that are TOO good, and can't speed-bin the lower end without tossing in a good amount of faster processors. Locking them up allows them to keep volume and product on the shelf without worrying about losing sales on their high end, due to the fact that smart overclockers will take it and run it to high end performance levels.
imo, if this comes to pass, speed-binning has failed at Intel due to the high quality of their processors. Odd disadvantage, eh?
