Here's AMD's 4x4 platform roadmap for the end of the year.
The company will release three new processors for this platform with Socket 1207, the FX-70, FX-72 and FX-74. It's said that these processors will only be sold in sets of two. The new FX lineup is based on the 90nm Windsor-core and has a thermal design power of 125W and 1MB L2 cache.
There won't be any new AM2 processors anymore with the "FX" brandname, but it is possible that AMD will release the FX-74 with a AM2 socket as an Athlon X2 6000+.
By the end of this year AMD will release its first 65nm processors. All of them will have a 65W thermal design power and the maximum clockspeed will be higher than what AMD initially told the press, the fastest CPU isn't a 2.4GHz one but a 2.6GHz chip.
