Per a Leupold tech today: The VX1 and 2 ( and maybe others) are being replaced with newer models. He would not give out any details about model numbers, etc. Said they will most likely be introduced at the Shot Show in 2018. When I called, I was number 52 in que, left a call back number and got called a little over two hours later. I asked about upgrades to the FX II line and got no info.
