A desktop roadmap doesn't contradict a mobile roadmap. These are different products. It's no secret that desktop isn't intel's priority.
Any roadmap has three fundamental pieces: reality, probability, and fantasy.
As far as the reality and probability stories are concerned, I could enumerate several reasons as to why the 14 nm node is proving to be difficult both for the foundries and Intel based on publicly available information.
If there is any way to prove out a new process, it is with memory or programmable logic, mostly uniform structures that can be replicated easily. As such, I would prefer to watch the Altera and Intel deal for their 14 nm node. There is also some basis in their earlier cooperation on "Stellarton", a primitive attempt at an Atom core and some FPGA gates in a single package.
I personally expect the first part on their 14 nm node will be an Altera FPGA - sampled, count them, there is one.
