The Thrust & Dirge set popped up a few days ago and is in-stock on Robotoybase (affiliated with Tony / chimungmung, who has always been awesome with selling)

From this, I imagine that Amazon will eventually get them in stock.
If you can't wait, it's about $150 USD from robotoybase and shipping is likely to run you another $50 USD. (I recently placed an order for some 3P figures. Only EMS was/is available).
