The refurb list I saw shows it opening Feb. 1. I called the reservation line and even though the hours aren't posted yet they let me book a PTN package. Not the same as WOC, but it's worth a try on the reservation line. The first time I called they said it wasn't available. The second time they checked and booked with no problem. I would call until you get the right person.
I hope I get to see WOC when I'm there in February, but I think I'll take my chances with a fast pass. I don't want to be limited in what I can order when I eat at Carthay Circle. The menu looks too good.
