The thing to watch is then going to be the "5700X", i.e. the Zen3 version of the 3700X, which, if the analogy matches, should have 8 cores and a 65W TDP. It isn't in the initial slate but they left room for it in the numbering.
Well I hope they release the 5700X soon. I was excited for Zen 3, but their price bump and lack of a middle ground option left me conflicted whether I should shell out more money for a 5800X or get a last gen CPU.
