According to DigiTimes, it looks like we'll see the AM2's & S1's by the end of the month after all. This is in contrast to the previous reports of the launch being delayed till early June.

"AMD will launch the Turion 64 X2 mobile platform on May 17 and AM2-compatible processors on May 23, as opposed to rumors of a June 6 launch for the desktop segment and an unspecified June date for the mobile CPU, according to sources at the motherboard makers."
