Down in San Diego, Marvel is releasing concept images of each of hero from Avengers 2. Today was Quicksilver's turn, but with a hidden easter egg of The Vision hovering in the background.

The Vision is a robotic hero that breaks away from Ultron's control to help The Avengers take down the sentient machine.

Rumors referencing "The Twins" appearing in the end credits of Captain America: The Winter Soldier are surfacing. The leading theory is that these twins will be the mutants Wanda and Pietro Maximoff, aka Scarlet Witch and Quicksilver, two Avengers main-stays.

Joss Whedon has already confirmed the two characters for Avengers: Age of Ultron. It makes sense that there would be a nod to them in Cap 2 since it's the final Marvel Phase 2 film (not including Guardians of the Galaxy) before the Avengers sequel premieres next summer.

Looks like Captain America and Black Widow might need some help wih Hydra's experimental twins. Here's all of ET's Avengers: Age of Ultron behind-the-scenes interview.

It's happened before.
