Anyone thinking FM1/FM2/AM3+ will completely take over are in for a surprise
Some Phenom II CPUs have been pulled from the market, but it turns out that wasn't the start of a general CPU decline.Assuming Fudzilla has accurate information, the Athlon II, Phenom II and Sempron CPU series will still be out and about two years from now.
That means that AMD won't kill AM3 socket CPUs in favor of AM3+ any time soon.
In other words, while FX 8350, 8320, 8120 (Vishera) and all other FX units will get the AM3+ motherboard they need, they won't be the death of AM3 boards.
Phenom II X4 chips (quad-core) will retire by the second quarter of 2013. The Athlon II X4 and X2 though, as well as Sempron units, will stick around though, or at least will get successors in one form or another.
