No ones going to know without getting these scopes out in various conditions. Even those that attended shot show don't know for sure as a lot of scopes look good in a controlled environment. Those at shot can know if they liked the look and feel of the scope, however.
Thermion
XP lineup should mirror performace-wise the Trail XP line as it keeps the same resolution and micron count. Alan D, since you are looking for a long range scope and didn't like the Trail XP, it's probably not worth it to you but the new form as well as colored backgrounds and reticles may be worth it to others.
XM lineup may be something to look at. They will come in 3.3, 4.2, and 5.5 for base mag. So, it will have less FOV and more base mag and have recording and built in batteries over your Apex. The big question is how will a 12 micron 320 res core compare against your 17 micron 384 core. When you move up to 5.5x base mag on the XM50, my guess is you may be sacrificing a bit of picture quality, but it is too soon to tell.
Hunters shooting bolt guns who want a thermal, should be really excited about the thermion as it should fit their guns much better than a lot of the traditional thermals.
Trail XQ LRF: Most people seem to like the rangefinders. It is a nice feature but the question comes down to is the price worth the premium? The image is the same. If you liked your Apex XQ 50, you could go Trail XQ50 LRF. It will have the exact same picture as it is the same 17 micron 384 with a base mag of 2.7x, but you gain recording, LRF, streamvision, and built in battery packs. The big question is what are those features worth to you.
N-Vision: I have nothing to base this on but what I've read but the N-Vison Halo will have the same core as Trijicon but with a 50mm and 25mm vs 60 and 35mm. They will have a 5 year warranty and be about 1-1.5K less expensive. Personally, I think this may be attractive to buyers. Not trying to speak for Tom, but he has mentioned he thinks most would either just buy the gold standard (Trijicon) or maybe get a Pulsar XP50 vs the N-Vision.
Personally for my use of thermal having an option with a battery pack and recording video are two necessary items. For others, it is probably different. Due to this, I probably won't go to N-Vision at this time, but I am intrigued.
