I went back to Eotech's booth on Wednesday morning. Then I looked at my Razor Gen3 this morning (just got home). I would submit that it's not quite as bright, BUT the Eotech is also trying to light up a lot more of the reticle (especially the circle at 1x), and this may impact what they're able to get out of the illumination system. I also don't know whether brightness would fall off due to the scope being on blast for days at a time at SHOT or whether they were swapping batteries. I did not hear anything about battery life, but I would not expect it to be radically different than what we've seen from other FFP LPVOs in this price range. Side by side review with the gen3 under tough lighting conditions is really the only way to properly compare.
Someone asked about 1x reticle visibility, and it's very good. The big fat circle does a good job of luring your eye to the center dot, vs the thin "wings" on the gen3.
Blackhound's mid-range 1-6. But if they can do it, I assume it will be a thing that others can pull off, such as Athlon. The reticle was somewhat disappointing due lack of holdovers (eg, the Razor Gen2E isn't out of a job yet), but it was definitely a fiber optic dot. (Blackhound's top end scopes are made by JOL in Japan, in case you care.)
