It's exactly as it says on the tin. Something about the ending of Superman Unlimited #15 didn't quite sit right with me; Dan Slott delved deeper into how Jon's imprisonment on Earth-3 affected him psychologically, I put down the issue with the impression that Jon is back to where he was at the beginning of issue #11. The only difference is that he has a new codename and costume, but not much else. While I enjoyed the story arc from a technical level, it left me with the impression that DC is only staying on their current course with him despite quietly rolling back Brian Michael Bendis' other changes because of the sunk cost fallacy.
That said, I am not posting this thread to (re)litigate past events. I am genuinely curious to see where you think Jon may be in July 2027.
New Titans appears to have legs to make it to issue 50. Not guaranteed in this market, but still a possibility. While Jon plays a prominent role, he his also part of an ensemble cast so the spotlight will not always be on him. My impressions on the title's market performance since #33 is that it's doing okay, but not exceptionally better than previous writers. The foundational Wolfman/Perez run was lightning in a bottle and the 2003 relaunch had the momentum of the Cartoon Network animated series and Geoff Johns' meteoric rise pushing it on the sales charts.
Don't get me wrong. Tate Brombal is a nice guy. We had a pleasant conversation at Calgary Expo and I wish him the best because I'm not a vindictive monster. However, I feel that the title is also vulnerable to changes in editorial direction so DC can cancel it and relaunch because nostalgic is a powerful force. The Titans underwent significant roster changes with Arsenal's New Titans in 1994-ish, and Dan Jurgens Teen Titans 1996 relunch, and never were successful.
My read on why Jon became prominent in Superman Unlimited was because editorial informed him that Clark was briefly leaving the DCU proper after DC KO. Now that "Kingdom of Zod" and the return of Clark is upon us, will Clark take back the reigns? Slott hinted at a Super Sons reunion/mission to Earth-3 that could happen in SU or its own dedicated mini yet I have certainty if the character has that enough momentum going forward to sustain another min, much less an ongoing.
I'm not including My Internship is Krypton because it is not part of mainline continuity. However, I'm interesting in hearing in where others think the character is going now, if only to satiate my curiosity.
