The Athlon will remain their high-end product for quite some time. They will however be introducing the new revision of the core, called Palomino, soon I think. The only difference will be that it will produce less heat, hence allow for higher clock speeds. They'll also be moving gradually to only 133mhz (=266) bus CPU's. I wouldn't wait for the 133mhz bus CPUs to be widely available because with the right mobo, all you have to do is lower the multiplier and switch the bus to 133mhz with normal T-birds. Palomino might be worth the wait, since 1.2ghz chips can get pretty hot...
