AMD is altering their roadmap for the Phenom processors, which they have done more than once in recent time. Several of the planned Phenom desktop processors are not going to make it to market, including two models of Phenom based on the 65nm process. The Kuma processors, which were originally on the schedule to be released this month, won't be seeing the light of day. Instead, AMD is still betting on the X2 to be their primary dual core offering. Apparently, AMD has decided that the Phenom FX also needs to be put on hold until they have finished getting their 45nm production lines ready.
This adds on to further complications AMD is apparently dealing with in the Phenom line. We first heard hints about this last week when it was rumored that AMD would be halting dual-core Phenom plans altogether, not just for 45nm variants.
