I don't think this new Mjolnir has anything in common with the hammer of Ultimate Thor outside of appearances.
io9: Speaking of that hammer - you've been playing a bit of a long game with it! It showed up in Thors, in the hands of Ultimate Thor. It's going to be playing a major role in the series, and Odinson will be wielding it. Tell us a little bit how it comes into the picture and where did the groundwork for this connection began.Aaron: Well, you know, it was - by ending the Ultimate universe, we knew we were kind of given this lump sum of those characters. So, part of my goal with Thors was [to do] the final story for Ultimate Thor. We talked about wanting to make those Secret Wars miniseries mean something in terms of the bigger picture still unfolding, that they weren't just four random issues you could forget about named Thors. I wanted something big to come out of Thors that would affect our characters going forward, so that turned out to be a hammer. This is just a great, great beast of metal.
So to have that somehow fly through the events of Secret Wars and land in the normal Marvel Universe, which we saw at the end of Thors, at Old Asgard - of course it went back to Old Asgard, but the old Asgard, nobody lives there. So, it's just been sitting there, all this time.
Here is the scene from Thors(also written by Aaron) they are referencing:
As you can see, it is an immediate tie-in to the current events of Unworthy Thor.
