You’re right about the WoB and BoW kits; I don’t think those had a ‘preorder’ phase. They were released at full price and in stock, though there has been coupons since that dropped it sub-$100.
Something else to note though is that the BoW/WoB kits have the numpad kit included. A lot of the newer colored sets (like the referenced Skiidata set) do not. I didn’t realize it till now, but if you can catch the BoW or WoB kits on sale, they’re a surprisingly good deal.
