1. I think it is safe to assume that the 3 of coin is just being added to his existing inventory (no discussion on Xur this stream, maybe on the next) 2. try to get as many exotics as you can before the drop, this way you have the blueprint for their year 2 version in hand already and you only have to grind for marks and not search for the exotic all over again. 3. no list yet but not all of the year 1 exotics will carry over 4. no word on this yet but they will likely come from engrams and possibly from Xur
