Evidently, while Cannonlake (the 10nm next gen chips for low-power SKUs) got punted to 2018 [0], Coffee Lake (the 14nm next gen chips for desktops) are still on for 2017 [1].
Desktop Kaby Lake launched last month, portable Kaby Lake started shipping to OEMs Q2 2016.
Intel used to try for a tick or tock every year - so Sandy Bridge in 2011, IVB in 2012, Haswell in 2013, then Broadwell was incredibly late except for a handful of SKUs in 2014, Skylake in 2015, Kaby Lake (mobile) in 2016...
Really the problem is that Intel ends up having these staggered releases, probably to address limited yield on their new processes and the most impact/value (since they've been so focused on improved work per watt, and mobile cares about that for a lot more than just heat dissipation reasons...)
