So I found bdaddik on eBay has Vader #3 in stock already. I placed an order with them and cancelled the Toy Palace pre-order. Should be here in about 2 weeks!
My Vader v3 arrived today. He looks really good. Attakus did an excellent job. The lightsaber needs to be. inserted into his hand but it actually looks fine without it too. Reminds me of Attakus V1.
