Are you certain? But we still don't have quad core Broadwells, let alone Skylakes?! Are they going to skip Broadwell quads?
I remember reading somewhere that quad Skylake is pushed to 2016 - but I could very well be wrong. If high-end Skylakes do come this year, it would certainly be interesting.

I think you misunderstood me - while one is mobile and the other desktop, they share the manufacturing process and many other things. This year, mobile Broadwells appeared but the desktop-class quad core CPUs (both mobile for MBP and desktop) were delayed (and are still not available).
