Many thanks to SWLing Post contributor, John (VA1JG), who notes:
As per the following exchange on the Yaesu Facebook group, the FTDX3000 is the latest Yaesu HF model to be discontinued:
Many thanks for the tip, John! I’ve noticed a number of retailers have listed it as discontinued. If memory serves, I believe this FT-DX3000 was first introduced at the 2012 Hamvention, so it has had a decent market run. No doubt, the new FT-DX10 will be Yaesu’s focus in this price bracket.
