When i was debating v2 or v3 someone gave me some good advice. A great preamp will always be good, however adc, jb3, 440, fill in the blanks will always be changing. I can for see having the v2 for a Loooooong time. However, everything after it will be changing regularly. What if the uber adc is in development right now? Not to knock v3, great piece of equipment. Great one box sollution. Opti mod is so perfect. V2 vs. v3 is a win win debate.
