We all know the drill: I don't/won't spoil on the day of release, but others might. So beware! You've been warned!
But, in general: Really, this issue pretty much was what you expected, if you've read both Avengers and New Avengers, recent Marvel history dating back from the creation of the Illuminati through Planet Hulk/World War Hulk to now.
It went the only way it could, after the last issue. And once you read it, you can get a pretty good idea how "Time Runs Out" is going to be structured, at least at the start.
I think Hickman played fair with the characters, as they've been portrayed for years now. It's been interesting reading the thread for NA 21 -- I've enjoyed the debates, and I've read all the posts -- and, again, I think it's fine that Hickman didn't let the characters off the hook.
Certainly, we can debate how they got there, in the respect of how the comics industry got them there. But this issue...it's a subtle little issue, in a few ways. There is definitely fodder for creators to mine in years to come, should the Marvel Universe remain relatively intact after "Time Runs Out."
*Sniff, sniff* "Damn it, Diana...If I'd known they would trade us in for a JT Krul-written Captain Atom and "The Savage Hawkman," I'd have let Superboy-Prime destroy all reality.""Superman flies and is really strong...what the fuck else do you need to know?!"
