OH! Also... I was bouncing-out-of-my-chair excited when they namedropped Madripoor (let alone went there). This has so much potential for what Marvel does and where the larger story goes in the future. Madripoor was introduced in The New Mutants, and many of its appearances were when Wolverine was doing shady stuff there. I don't think most, any more, but still likely the majority of it's comic appearances have been mutant-related.
Also Viper ruled Madripoor for a long time.
Also also, just like the Discworld is on the back of a giant turtle, the comics revealed Madripoor is an agglomeration of land on the back of a sleeping dragon who the Hand awoke -- and I know Marvel have hinted that they may bring Daredevil, at least, properly into the MCU. Whether they go that route or not, there's a lot of stuff that isn't presently a part of the MCU that there have been stirrings about (Daredevil, Sinister Six, mutants/X-Men, Fin Fang Foom), and Madripoor has ties to most of them. I am betting this isn't the last we see of this place, by a long shot.
...Oh, and what I wouldn't give to have Longshot and Spiral and Mojo come in at some point...
