I'm thinking maybe the Edition will be be upgradeable as there won't be many of them and Apple be more hands on with Edition customers. I think there's no way the Sport will be upgradeable as there would be too many of them and can't imagine logistical how they will pull that off. But how about the stainless steel Apple Watch? And if the stainless steel is upgradeable, I'm thinking you would trade-in gen 1 for gen 2, while for the Edition the Apple Store would actually switch the processors out. Or perhaps Edition customers would mail them in? Just trying to imagine how Apple would implement an upgrade program and whether it would make sense for them.
