derk, don't hold your breath, it is doubtful that Vortex will release any new AMG scope in 2019 and even if they did, I believe it took over a year for Vortex to get the AMG 6-24 orders to settle down before they were widely available. Also, it is doubtful the AMG line will show anything other than a 4x erector anytime soon, maybe a 4-16 or 4.5-18 at best is what we'd see. Of course, I do not have inside information, this is only speculation based on the information I have obtained. That being said, would absolutely love to see a lightweight 3-18 or 4-20 from the AMG group! Don't ever let the "possibility" of a scope hinder you from purchasing a scope that actually exists if you feel it will help you. If you buy from one of the Hide Dealers you will usually get a great price and if it's a hot item scope (like the Mark 5HD line) then even if you do decide to sell for another option you should not lose much.
I am not expecting much from SHOT 2019 in regard to scopes that will fill a niche that doesn't already exist, sure we'll see some new scopes from manufacturers. Maybe an XTR III line from Burris with upgraded glass and SCR type Christmas tree reticle, hopefully the 3-21 FFP Hunter series that Schmidt & Bender teased us with the tiger stripes at the 2018 shot, maybe a Minox lightweight ZP5 line. My hope is that more manufacturers will strive to find ways to reduce weight while increasing optical quality and erector range, more lightweight 5x-6x magnification long range scopes would be great. Would love to see more manufacturers adopt the 4-20 range of scopes - a Vortex PST II 4-20 would be a great "budget" option that fills the gap between the 3-15 and 5-25, if Burris can do it why not Vortex. Be fantastic to see Steiner/Burris, Nightforce and Leupold come out with a Christmas tree mil reticle similar to MR4, SKMR3 and Gen 3XR.
