It's difficult to make out in the cover image but Cap's new suit features The Avengers symbol (the "A") on his arm - something we'll be seeing from the new team as they use Stark's tower as their official base of operations and get new costume and equipment upgrades. Cap's Suit and an early makeshift version of Ultron appeared in unofficial set photos previously and we've seen the other Ultrons (in the background of this cover) in the first official Avengers: Age of Ultron concept art (one example below featuring Aaron Taylor-Johnson's Quicksilver).
The most interesting information is the quotes and story details the EW cover story also provides about Ultron's new origins. Hank Pym a.k.a. Ant-Man creates Ultron in the comics but we know Joss Whedon is changing that up for his film and what we suspected last year about Tony Stark being responsible is true. With S.H.I.E.L.D. no longer serving as Earth's defense and first response against the unknown and other-worldly, it's up to The Avengers. And to help them out and given them a break, Stark develops Ultron, a sentient program, an artificial intelligence that will help him to serve as an Avenger without actually suiting up himself - building off of what we saw in Iron Man 3 where we met an Iron Legion of automated suits in the final act.
This self-aware AI - perhaps an evolution of JARVIS from the Iron Man films and The Avengers 1 - can locate threats and control Stark's legion of drone suits to deal with them... until Ultron decides that humans are the greatest threat. Joss Whedon, while smiling and rubbing his hands together:
"Ultron sees the big picture and he goes, ‘Okay, we need radical change, which will be violent and appalling, in order to make everything better’; he’s not just going ‘Muhaha, soon I’ll rule!' He’s on a mission. He wants to save us."
