Is there actually any reason to believe this isn't just a straight re-issue?
Maybe the "2.0" is applied to the box, just as a way of distinguishing the two releases from one another. The original is pristine, the re-release has the big "2.0" stamped on it. That way, the "first edition" release can still be considered more "valuable" by collectors (as it's a true first edition), while all the new collectors and those who don't care about collectibility can get another chance at owning the exact same figure for the sake of the figure itself.
And that way, those who have the original version don't feel like they have to buy the exact same figure again, because it's not "improved" in any way and has exactly the same contents and accessories.
Sort of like books - the "first edition" for very famous books can be worth something, but if you just want to read the story, then a later edition isn't any less desirable to you.
