It looks like Intel is prepping a huge list of chipsets under their 300-series platform roadmap. The chipset lineup will include the already known Z370 which is launching next month, followed by a range of enthusiast / mainstream consumer and corporate options that will be available later in 2018.
Intel Z370 Chipset Confirmed For Next Month Launch, Z390 Also Headed As Enthusiast Option in 2H 2018 - LGA 1151v2 and Coffee Lake Processor Compatibility Maintained
The Intel 300-series platform consists of two main products, the 300-series motherboards and the Coffee Lake desktop processors. The initial launch is aimed for Q4 2017 and will include a range of Z370 chipset based motherboards and several Coffee Lake desktop chips. These processors will be a range of unlocked and locked SKUs that will include Core i7, Core i5 and Core i3 branded chips. A new roadmap has now been leaked over at Anandtech Forums which details the full list of Intel 8th gen, 300 series chipsets.

We have confirmed that Intel is launching the 300-series platform on 5th October 2017. The launch will have an army of Z370 boards but for those planning to build more budget tier PCs will have to wait till early 2018. The roadmap details that Intel's consumer lineup will feature four chipsets. The first is Z370 which falls under the enthusiast segment. The mainstream segment includes the H370 chipset while the Value segment includes the H310 chipset.
