The expected launch of Intel Kaby Lake dual-core processors seems to be confirmed again. First-gen chips (with DHCP 1.4) should be released in September, chips with the new stepping (and DHCP 2.2 support) in the end of December or the start of January in combination with the quad-core processor from the S- (desktop) and H-series (mobile).
