Future Intel processor lineups have included almost a half dozen rumored codenames, but at long last we could finally have the details pinned down thanks to a leaked Intel roadmap.

Xfastest posted slides of what it claims to be an official Intel roadmap outlining the processor release schedule for the coming year. Going by the schedule, and disappointingly, we shouldn’t expect 9th generation Intel processors until the first few months of 2019. The Intel roadmap lists that the Core i9-9900K, Core i7-9700K and Core i5-9600K will all release in the first quarter of 2019.
