I would be surprised to hear it!
I thought Morrison was just doing his thing without aiming at an actual endgame. I really enjoyed season 1, which is amazing since I'm not a Hal fan, but I decided to trade wait season 2 so I'm not totally sure what's going on there.
I think I heard about the new Guardians....that does sound familiar, and I guess Hal's back on earth for a lot of this season. So, what, is the endgame just Hal galloping off into the sunset? Or.....star..set? I mean, that's sort of fitting for the whole maverick space cowboy thing I guess but there's not a lot of meat on that bone.
I can't speak for Wonder Woman either, but nobody seems worried about giving her the same kind of "next life step" send off Bruce and Clark are getting. I dropped the book (again) but it seems like her creative team is still a revolving door and as far as I know there's been nothing like her having a kid or getting married or retiring or becoming queen or any of that (I do try to keep up with developments). But Diana doesn't have the deep setting and status quo Clark and Bruce do, her world is constantly being re-imagined by creators who have no incentive to continue with what's come before, and she's immortal so maybe DC doesn't feel the need to endgame her.
And if Vordan is right and Kaldur becomes Aquaman, that's a 5G book I will actually buy! I've heard the current book is pretty solid but I'll grab trades when all the crazy ends. But Kaldur as Aquaman would get my money. Jon as Superman might get a shot, depending on the creators and the hook but Kaldur as Aquaman is an automatic purchase.
