I am not part of Burris, so my opinion does not really have much weight here, but I fully expect to see some new stuff in 2018 in the XTR line. I am not sure of the exact timeline, but I assure you that Burris pays attention to what the market is asking of them.
Hoping for more rock solid illumination and better turret adjustment. Not too concerned about glass. Rocking a 1-4 vortex pst on my ar15. Doesn't bother me.
