DailyTech has some pricing information that suggests AMD plans to cut single-core Athlon 64 and Sempron processor prices on May 15, just a week before the expected launch of Socket AM2.  Allegedly, the Athlon 64 3500+ and 3200+ will go down from their current $208 and $154 prices to $185 and $135, respectively. Meanwhile, Socket 754 Sempron 3400+, 3300+, 3100+, 3000+, and 2800+ chips will reportedly go down to $95, $91, $81, $76, and $65. There is no word yet on whether AMD is planning any price cuts for the rest of the Socket 939 line.

The price cuts are quite nice. I'm particularly glad that Semprons will all be under 100 bucks, it seems to me that there was too much of an overlap between the low-end A64s and the Semprons.
