Sign me up as another wanting the real Jon Kent back. And undoing the crap story Bendis did that not only led up to the age-up, but undoing the crap parenting and marital relationship of Clark and Lois. Because, man, that was just plain awful.
I could also get behind the real Earth 2, 3, etc. I would like crossovers that DON'T involve some random reality warping Crisis to do so though. I also agree with garazza on the whole "creating a character solely to take a mantle". Yara, Jace (may as well be), and fake Jon (the one time I've seen any personality, was under the Super Sons writer) are all OCs. Nothing previous to establish them, just tossed into the mantle, ignoring characters that had long existed to take up said mantle. Look at Tim Drake, literally made "to be Robin", to the point where most current writers keep defaulting him back to Robin because what they do write, well, is lackadaisical, at best. Red Robin worked, until they Mary Sue'd him in New 52.
After that, I want this to be the last event like this, for at LEAST 5 years.
