AMD's Zen 2 and Zen 3 7nm are in the pipe
 

Mark Papermaster confirms

One thing that you need to think about after the launch of the Zen and EPYC is that the company's CTO is claiming that Zen 2 will continue as a success story.

Mark Papermaster and a few others executives including Scott Aylor, have repeatedly said that the EPYC follower is built to be a leader. AMD wants to continue the execution of its roadmap and it wants to lead.

Mark confirmed to Fudzilla, that this is not a one-shot product, AMD has Zen 2 and Zen 3 in the pipeline and for the enterprise / server market, those are the Rome and Milan.
