I think this is the first picture I've seen with the V2 and V3 side-by-side, point for posting. Also - is that a Nemesis?
Yup, that's an older VA Nemesis that Artorius had (it's rather on the pink side so it's probably closer to Bane's Heart). I took that photo a while back when we had some of our sabers laid out, just because I thought the progression was pretty neat - we think of that particular hilt as a "Prophecy V0" really.
