That being said, I'm not talking about branching timelines. I'm talking about the new line of DC stuff is one of the already available multiverses (unless they labeled all 52 different multiverses already.) Doesn't Gotham by Gaslight and Red Son still exist out there somewhere? I'm not the biggest DC nerd, but... I assumed that was the case, unless Countdown and all that shit changed it.[/color]
My understanding is that many of the Elseworlds stories now exist on one of the 52 universes.
I was under the same assumption. Since 52, as far as I'm aware they've rarely used the other 51 universes aside from Earth Prime with Superboy Prime in Adventure Comics and Earth-3 with the Crime Syndicate recently in JLA. Even taking that into account that leaves 49 other universes. Now my guess is that if this "relaunch" doesn't pan out the way they want we might end up seeing one of the other earths remaining much like the current Earth-1 and a crossover event much like Crisis on Infinite Earth's play out again.
The thing with Booster Gold and time travel that's confused me at times is that sometimes they tend to pick and choose how solidified time works. Up to now we've been told that time has to play out the way it happens and you can't go back and make changes; the best recent examples were that Barbara Gordon had to get shot by the Joker and Ted Kord had to die. Yet Booster was able to go back and go on adventures with Ted off planet; thus altering history not just for Ted, but also for the people they interact with that they wouldn't have originally. There's also the fact that Booster himself is a disruption in time simple for being in the 21st century, and going by how they brought back his sister, anyone from the future can't really stay dead because they can get pulled from a time in the future before they die in the present/past.
My guess is that whatever Eobard Thawne (The Reverse Flash) did screwed up the timeline so bad that there's no way to get it back together 100% exactly the way it was... Which now that I think of it leaves another backdoor for things to go back to "normal" with a Booster Gold event.
But that's pretty much all speculation seeing as how Flashpoint only just started.
SIDE NOTE: Am I alone in thinking that this whole relaunch feels like an attempt to start a new "Age" in comics? If so what would we call the past 26 years? Or would this just be a post-modern age? Not saying that will happen, just a "what if" thought.
