Transitioning to 10nm isn't expected to be any better, so Intel is extending the timelines. Cannonlake is being pushed back, from 2016 to the second half of 2017, and in the interim, a third "lake" generation processor will be released in 2016. Like Skylake, this processor will continue to use the 14nm process. News of this processor appeared to leak last month along with its full name: Kaby Lake. Little concrete is known about Kaby Lake, but it's likely to be available in a range of lines from a 4.5W laptop part up to 80W dual-socket server and workstation parts.
Since selling my 2008 MacBook Pro a few years back, I've been patiently waiting for a newer architecture and design replacement to Apple's current 15-inch Retina Display. With Broadwell's deployment stagnant and almost non-existent, I'm hoping they just skip it and go straight to Skylake for a Fall release. I was definitely disappointed with the latest spec bump still on Haswell but at least the change in dedicated graphics cards helped increase processing power by 70%. Maybe I'll "settle" for that!.
