However, the soon-to-be-released Z370 chipset will not have 802.11ac R2 WiFi (+ Bluetooth 5.0) and USB 3.1 support. Intel reportedly planned to release the Coffee Lake platform in 2018 but moved the launch to August 2017 to better compete with AMD's Ryzen platform. As a result, WiFi and USB 3.1 didn't make it into the final version of the Z370 chipset.
However, other 300-series chipsets including the Z390 and H370, planned for early 2018, will support Wi-Fi and USB 3.1 Gen2. The Gemini Lake platform, which is expected to release at the end of 2017 to succeed Intel's entry-level low-power-consumption SoC Apollo Lake platform, will also have integrated Wi-Fi support.
The sources pointed out that the impact to chip suppliers will become more obvious in the second half since Coffee Lake's penetration will not be high initially.
