Since the MCU began with Tony being captured by the Ten Rings, I figure that it'll come to an end with the Ten Rings as the antagonists.
2099 as in hulk 2099, spiderman 2099 (I think there's a iron man 2099)
Spider-Man 2099 is my favorite Spider-Man iteration, I'd love for him to appear.
My fav spider is noir spiderman
Plus another thing, the ten rings pop up twice, in iron man 3 and in iron man 1
More than that, they're in all 3 Iron Man movies, plenty of tie-in comics, Marvel One-Shot: All Hail the King, and Ant-Man.
How in iron man 2
In Iron Man 2, Vanko meets with an Ten Rings Agent to get the ticket to the race event Tony would be at in Monaco.
Oh ok
But what has vanko got to do with ten rings
They both had a common enemy...Stark
What do you think?
