Part of me is worried that "The Lies" will be a way to sweep large portions of the reboot under the rug, but A) Rucka sounds like he intends on respecting the seven years between his lastrun and B) This timey wimey stuff is exactly how I'd go about fixing the X-Men if I were in charge.
I'm not sure, without knowing how he's going to handle the interplay between "Lies" and "Year One," how to go about sorting "truth" from "lies" (about done with these quotation marks, don't worry). There are certainly a few things I'd want to stay put:
-ARES. My absolute favorite part of Azz's run. His role in Diana's life and his eventual death are plot threads that will always offset the sex piracy in my mind.
-Demigod Origins: like borntohula said, I think it expands her story a lot.
-rotating supporting cast: I'd be glad if Steve Trevor and Etta Candy show up in Year One issues, but I hope that new faces continue to show up in the Sharp issues, as well as what few characters survived the First Born's Reign on Olympus. Wonder Woman is all about being kind and hospitable to strangers, right?
