This means that there are TWO different versions of the Retro Duo. I am assuming the 2.0 is a revision of sorts, but I was wondering what changes, if any, were known.

Well, obviously it has POWER SWITCH V2.0.
That's a pretty big upgrade in and of itself.
In all seriousness, though, mine says V2.0 and the box art is different than what you posted.
It just has a straight on shot of the console.
