Thorton's are already being sold, but they're on stores shelves as just Athlon XP's because that's all they are. The only difference Joe Enduser would notice is the size of the die.
All of this hype over a CPU that was manufacturered because AMD discontinued a product before all of the orders were filled is crazy.
Matter of fact, I got an email today from AMD that said that they have already discontinued the 2000+ and 2200+ Thortons, probably because all of the orders that needed to be filled were filled. That means the only thing coming out of AMD's fab now should be Thorton 2600+ CPU's and Bartons. Now why would AMD affix a new name to a CPU they don't even make any more?
