I've received my rail for the X axis, (going to reuse the lead screws for the Y axis 1/2-8 8 start) just received notification that the K2 has shipped. Ordered the 8020 last week, should see it sometime this week. So if all goes well, and Harry has my order completed on-time I should have all the parts needed to start the upgrade by the end of February or first of March.
