In an article from benchlife.info new information concerning Kaby Lake was revealed. Kaby Lake will launch next year after Broadwell-E. Kaby Lake resembles the Haswell Refresh Devil's Canyon launch in the sense that there is no transition to a smaller process node and will come with a chipset refresh.
The 200 series chipset features an increase from 26 to 30 PCIe lanes, support for Intel Optane Technology, and support for both Skylake and Kaby Lake processors.
Kaby Lake's key features include a core performance increase (which we didn't get with Haswell Refresh!), dual and quad core processors from 35W to 95W, and shift to 5K resolution. Important is that Kaby Lake will be compatible with the 100 series chipset and with DDR3L memory.
