I was able to get them on Walmart, even though it showed out of stock on some by opening the ones that were out of stock, then going to my cart (which had one that was in stock) and at the bottom it showed my previously viewed items and the pre-order option was available there.
i have a feeling it may just get cancelled, but it showed in my cart and allowed me to order..
Don't see them any up on Gamestop yet (but they always seem to be behind).
Omega was up on Amazon (as i think it was their exclusive).

They also had the carbonized 2 set for the Tie / Guard on sale for 30% off (the price it should have started at):
