The roadmap for Intel NUCs in the coming years seems to be a rather interesting one with a host of NUCs in different configuration options starting from the 10W 'Gemini Lake' Celerons all the way till the 100W Kaby Lake-H Core i7-xxxxK. NUCs based on the Coffee Lake and Kaby Lake-H CPUs also come with support for Thunderbolt 3 and Intel Optane memory.

Wow, still one year for the new 28W NUC!
J5005 NUC sounds interesting, I wish Gemini Lake would finally upgrade GPU from 5xx series to 6xx series, 4Mb L2 cache is already good upgrade, but more is needed!
