Good luck. You can get on the email list at 44rn.com but they don't restock them very often, and when I'd finally get a notice they were sold out before I could order. Recently picked up a used B&W camo edition in good condition from someone on the pedalroom marketplace. They pop up there from time to time so that's probably you're best bet. The bike I originally wanted to use a black Aarn chainring on I ended up just getting a Lattice instead, it's similar and pretty nice too (they also come in silver).
