Two production lines exist - RS-68 (Delta-IV) and RS-25 (STS & SLS). 1 is actively building (RS-68) and 1 is primed for production (RS-25).

I do not believe Rocketdyne is anything like "primed" for RS-25E.

RS-25D can restart construction in the meantime, all that RS-25E would be is a more economic expendable version to decrease carrying costs of the core engine.  The J-2x was only in the J-2 family in name only, pretty much was a brand new engine. RS-25E will basically still function as the current engine, but changes will be made based on availability of funds and potential savings.
And this is a good reminder that just because one of your fellow space enthusiasts occasionally voices doubts about the SpaceX schedule announcements or is cautious about believing SpaceX has licked a problem before actually seeing proof that's true, it doesn't mean they hate SpaceX.

What a great article. Enjoying going through what appears to be a huge amount of SLS articles. So glad I found this site, even if I was late to the party.
