TechReport has posted an article about the cancellation of the Quad FX. Here's what AMD's Suzy Pruitt told them:

The short answer is that while there are still engineering resources focused on future platform offerings that build off Quad FX, the current energy and effort has gone into programs and product initiatives like "Spider" and AMD has discontinued future planning and development of its eight-core enthusiast platform at this time.

We will continue to support customers that have an existing Quad FX with DSDC and are also working on an upgrade path for those customers. While AMD is not actively promoting AMD Opteron processor as a 2P enthusiast solution, we recognized that there are enthusiasts who are looking for two-socket solutions and think an Opteron platform is well-suited to meet that demand at this time.

So AMD has apparently dropped its enthusiast-class dual-socket technology direction. When TechReport pressed for further details on CPU upgrade options for current owners of Quad FX systems, Pruitt said the processor "likely won't be a Phenom-branded product," but could not give us an ETA for its arrival.

Oh well, I think things like Skulltrail and 4X4 / Quad FX are great technology solutions when it comes to video editing and encoding, but do gamers really need to be building or buying dual processor rigs while we currently have quad core boxes that go largely underutilized. Do you guys care about multiprocessor gaming boxes?
