Commenter Bob and Sean Whitmore at Comic Critics have the same general idea, and i agree, and i think we all saw it coming ever since Guardians of the Galaxy showed up in Avengers Assemble which as far as i can tell takes place entirely in the Movieverse.

Here's Sean Whitmore/@JoshCritic:

[T]his is the first time Marvel's been able to take a property with nothing currently invested in it and make it resemble the movieverse before the movie's even come out. Just as a minor for-instance: check out the "Council of Galactic Empires". We've seen this kind of thing a lot, but not with this lineup. Right off the bat, Spartax-which has been about as relevant to the MU in recent years as the planet Melmac-now has a front-row seat. Star-Lord even refers to his father as "king of the galaxy". He's being flippant, but the issue makes it seem like it's not that far off. The Brood are also present, which is weird. I can't imagine, say, the United Federation of Planets ever inviting Xenomorphs to their club. And then there's Annihilus, who should not only be at the top of every planet's hit list, but isn't even technically part of our galaxy. All of which means little except to reinforce my point that Marvel obviously views their cosmic mythology as particularly malleable. If nothing else, I'd wager Spartax will be a major cosmic player in the Marvel Cinematic Universe, akin to the role the Shi'ar usually play.

There's a point to be made about the futility of making your comics more like the movies to prepare for the huge influx of new fans that loved the movie and now want to read the comic book (it ain't happening, guys), but i'll skip it.

What's important to me is the fact that it's pretty clear that Marvel has lost interest in Marvel's continuity. I really take issue with the part i italicized in the quote above. Marvel actually did have something invested in their cosmic universe. They had a number of surprisingly successful events over the past several years coming out of those properties, and surely the buzz from that is why we're even going to get to see a Guardians of the Galaxy movie. They weren't top sellers, but they did much better than expected, and Marvel did an admirable job of keeping the books alive in various formats. And i'm going to argue that the reason they worked is because the creators (Giffen, DnA, and more) put together a cast from disparate parts of the MU and did a decent job of representing those characters in a way that was fairly consistent with what existed before. They worked within the existing framework (sure, there were inconsistencies and cheats, but that's always been the case). So that pulled in a lot of fans who remembered and were interest in those characters, and those fans didn't get angry and walk away when they were written poorly and out of character.

In contrast to that, from what i (and i think Bob, and @JoshCritic) can see in Bendis' GotG series, Marvel editorial is simply dumping whatever they don't like or (in the case of the Shi'ar, who are possibly tied up in the X-Men movie rights) can't use.

And i'm not here to complain (ha!). I just wish Marvel would do it clean. Close up the MU and reboot with something that can be consistent with the Movieverse. Let those of us who are really still hanging around only because we have a loyalty to the old Marvel Universe know that they're done with all of that. DC did it. Why not Marvel? It's time, guys. You've been hostile to continuity for a long time. Put your money behind your convictions and go for it.

I was going to write that Marvel can't do that because they know the vast majority of their fan base now comes from us older die hard readers. Other than the guy who thinks Bendis invented Rocket Squirrel, we're not really here for what you're doing now. We're here because it continues the story started by Lee & Kirby and was expanded on by many other great creators. It's why Marvel's tagline for Marvel NOW was "It's not a reboot, we swear!" and why they constantly have to come out and insist that Avengers Assemble and Age of Ultron and whatever else all take place in the real Marvel Universe.

I was going to write that, but i realized that's inconsistent with the fact that DC did it. DC rebooted their continuity and they still have readers. So really, there's no excuse for Marvel. If this is what they want to do, go for it. Heck i might even read a few of the books (in trade format, and if someone like Jeff Parker is writing).

I release you, fnord. You've been loyal, but you're loyalty has not been rewarded. You are released.

Some editor, he used "you're" when he meant "your"

It's probably true that Marvel fans still buying monthly comics would accept a wholesale reboot, since Marvel has been implementing half-hearted reboots for a while now. If fans stuck around after Brand New day or, heck, Teen Tony, they can probably endure a total reboot.

But it's hard to say: DC fans had to accept reboots as early as '85, when a lot of today's readers were just getting hooked. Marvel fans used to pride themselves on the MU's relative stability and consistency. But that quality gradually fell in the past decade anyway.
