Yeah, plus I don't think any of the champagne combos have just been "gotta have" or "gotta make that!!" combos. The original champagnes are cool, but beyond that, I don't think they're that much more special, already so extreme as is. So I imagine the price will fall fairly quickly over the next few years to easily under $1k.
Though if a super is produced, or some not yet produced combo is killer, that could change.
