The Open Beta closed up shop on Sunday, and since then they've been working to get their hardware setup squared away. The problem, and the reason the early access problem was shut down, is that registrations for the program spiked hard on Tuesday of this week. According to the statement: "Early on Wednesday the capacity limit was reached and automatically shut off. The entire program is now mostly sold out globally, with some local variation. We had no way of anticipating the spike we saw at the end."
What's interesting is that Closed Beta is apparently still running - they're milking that resource for data all the way to the end, evidently patching and fixing right up until launch day. In the meantime, disappointed early-access hopefuls are just going to have to wait for their chance at Hyborian glory.
