All that that quote tells us is the console and pc platforms are being rolled out at different times. Which works because they are currently separate, on different servers, I believe? PC users are all on the same servers, horizons or base. Presumably EDO horizons and base will all be on the same servers.Oooh.
Odyssey has a different engine in it, which also has an impact on the visuals in the base game. But only if you buy Odyssey.
EDIT:: Presumably this means that Odyssey players cannot instance with Horizons players on the surface of the same planet?
What I'm getting at is the only thing that question answers is whether the consoles and pc are separate.
