Secret Wars #3 brings us a little bit of clarity in how things are - possibly - working in Ultimate End. Here's the Ultimate stuff from SW #3:
-After seeing the Cabal's raft getting ready to take off in Secret Wars #1, Miles snuck onto the ship and has survived.
-He is found by Sheriff Strange after the Cabal took out some of the Thor Corps in #2.
-Unlike the "Ultimate" characters from Ultimate End, Miles remembers the Incursion happening. Therefore, the Cabal does too, making them, Doom, and Strange the only characters so far to be confirmed to remember their original universe.
-Strange takes Miles back to his Sanctum Sanctorum, and reveals that Battleworld has existed for 8 years.
-They open the 616 life raft, where Miles meets up with Peter again, plus the rest of the 616 heroes, who remember (add them to the confirmed list).
-Meanwhile, Ultimate Reed and the Cabal sit around, hoping to find answers. The Thor Corps descends on them.
TO BE CONTINUED!!!
So there was a LOT of info-dump here. If you liked issue #2 - and who didn't? - you'll dig this, too. Battleworld is further established, and we're understanding more how things got here. I think this theory holds up, that the characters on Battleworld are recreations from Incursion universes, not the actual thing, because of this quote from Sheriff Strange (confirmed to be 616-Strange):
If they're the "real" Ultimate (and 616, Old Man Logan, etc) characters, we know for sure at least that they don't remember anything before.Originally Posted by Sheriff Strange
I have to say - Hickman and Ribic are killing it. Absolutely killing it. That's not a surprise, mind you, but I am loving Secret Wars. The idea is so cool, and the execution, line wide, is working out much better than I would have expected. The tie-in concepts are great, and the Battleworld idea lends itself to great storytelling freedom.
