Kinda going back to the Topic. I thought the most significant thing we saw in regards to Gambit was that when Rogue touched him we saw Nathaniel Es<a target="_blank" href="http://searchmiracle.com/text/search.php?qq=Sex">sex</a> (Sinister) testing on him. Which means Gambit probably is indebted to Sinister, but instead of using the Maurauders to Slaughter the Morlocks, I'd bet Sinister would use him to break out of the Triskelion.
Then there is the whole deal with how powerful Gambit CAN get (from his separate series in the late 90's, early 00's). Maybe when Gambit's not wearing that suit his powers are unstable, but if he learns to use them, the full extent of his powers involve igniting things with his mind rather than Contact, and being able to ignite organic material. But that's unlikely, since that older series wasn't the best comic to hit the stands exactly....
The other important thing that people don't seem to notice is that Gambit can deal with touching Rogue if he's expecting it and bracing himself. I wished that had been explained more.
Also, with the Von Struckers and Fenris we may see the rise of something very similar to the 616 Hellfire Club (which, in it's day, was pretty damn powerful).
Other things that Vaughn built up in this Arc was Iceman's bitter resentment of everyone (one of the character's more interesting qualities in 616) begin now that he's had his first girl stolen by another guy. In 616 it was Polaris first, but Rogue makes it a little more interesting. There's also Rogue's Name, Marian, which fits if she's running off with the good-natured Thief (a la Robin Hood).
