Tweakers.net published some information concerning AMD's plans for the end of the year:
The AM2 Athlon 64 X2 will continue to evolve. In November, AMD will introduce three 90 nm models, the X2 5400+ and 5600+ clocked at 2.8 GHz and the X2 6000+ clocked at 3.0 GHz. The 5600+ is equivalent to the current FX-62, but the TDP is reduced from 125W to 89W.
The transition to 65 nm will be progressive with the release in December of models clocked at 2.6 GHz max. This let us believe that like with the change to 90nm, AMD will initially have some trouble with high frequencies. The TDP will be of 65 W as compared to 98 W for the equivalent 90nm standard version and 65 W for the Energy Efficient version.
To finish, it seems that the 4x4 platform (Quad Father) will change its name from Opteron to Athlon 64 FX since it won't be available with AM2 but with Socket 1207. If this information is verified, this platform will be even less interesting because it won't be possible for Athlon64 X2 / FX processors owners to buy a motherboard and only one CPU to use it. Anyway, according to Tweakers.net, Athlon 64 FX Socket F processor would only be sold by pair.
