I wonder where Marvel is going with all this time and space travelling nonsense.
Everything seems to be pointing to a reboot (or maybe "reorganization" is a better word) of the marvel multiverse.
Age of ultron seems to be the starting point, with Doom's time platform being used to screw with time, repeatedly. All New Xmen points out that this particular device messes with time in a unique way. All other time travel attempts simply create splinter realities, this one doesn't.
Age of ultron ends with misuse of the platform seriously damaging space time as a whole.
Those particular images were more like a time earthquake, so to speak. At that moment time, space, reality and all the parallel worlds are vibrating and shaking back and forth really fast. So you get a bit of a doppler effect as all of these various iterations or versions of characters and events begin to resonate and vibrate off one another as well as begin to be seen by one another.

A post AOU interview with brevoort.
All New Xmen starts with Beast using the time platform to grab the original 5 xmen for a really, really stupid reason. Especially so considering he's fully aware of what happened with Age of Ultron. All new Xmen leads into Battle of the Atom, in which we learn that if any of the teen incarnations of the original 5 are killed in any way, current continuity gets badly damaged. (i.e. cyclops disappearing from reality completely).
Jean is currently also getting more powerful very rapidly- she already has access to powers she shouldn't have had until she was in her twenties, and it's implied/stated that Xavier probably won't be able to mindwipe her even if she DOES go back. One way or another Jean's character and continuity will be permanently changed by ANXM/BOA.
BOTA continues with xmen from the future using the time platform AGAIN and coming to the present, saying the future is screwed because of the actions of the original 5. As we've seen before, using that platform can damage reality...badly.
Over in Superior Spiderman, We have Alchemax in 2099 finding that reality is breaking down because of what's going on in 616 right now. Tyler Stone is being erased from reality, and if he goes, Spiderman 2099 goes and likely 2099 itself along with it. (as no stone means no alchemax as we understand it, and alchemax under stone's leadership was responsible for pretty much everything in 2099).
That arc can lead to two possible outcomes- either spiderman 2099 manages to fix everything without complications and return to 2099 safe and sound (hilariously unlikely) or 2099 itself as a continuity is wiped out, with spiderman 2099 remaining a resident of 616, or killed/eliminated. The second is much, much more likely, as 2099 itself becomes problematic the longer marvel goes without "fixing" it. at conception it ("the future of the marvel universe") was a little more than 100 years away. Now it''s about 85. 15 more years (not that long in the grand scheme of things) and it'll be 70. Any earlier and the radical changes that have occurred become impossible/implausible and marvel is put in a very awkward position. It's not going to survive long term.
The Ultimate universe is DOA..marvel is wiping it out somehow. 616 Galactus is over there now, and we know that the Avengers and Ultimates will come to a head next year because of reasons. Ultimate spiderman will be rolled into 616, but the ultimate universe as a separate continuity is just going to be gone. There are VERY few things that can wipe out an entire continuity completely, and it's going to be a big event. Odds of it being related to AOU and all this time business are pretty high.
Infinity I'm less clear on- the damage to the multiverse has something to do with it, but the event doesn't revolve around it per se. I've just started reading it and really have no clue what the builders are doing or why they're wiping out planets.
HOWEVER, Thanos is currently on earth. The infinity gems are gone and shattered...with one exception. Guess which one? If you said "the time gem", give yourself a cookie. The time gem is going to reappear at some point during infinity, meaning someone in 616 gets infinite control over time, or very close to it. With the retcons done to the infinity gems over the past decade or so I'm not entirely certain as to how powerful it really is, though.
Xmen legacy getting canceled is new to me (if indeed it is), but as an "alternate universe" continuity having it around post restructure would be problematic anyway.
So there you have it- marvel is clearly on a path to restructure and/or wipe out a big chunk of the multiverse across their largest titles. I don't think they'll go full on "flashpoint" or "new 52" as DC did, but a simplification of the current status quo is inevitable.
