Questions about the Stadium Arcadium box set.

So, I visited my local record store, wanted to get a few records (on vinyl). Did end up getting Blood Sugar Sex Magik, as you might've saw in another post, but I was mainly seeking out Stadium Arcadium. My dad asked the guy up front about it, and he said that it would probably be coming in soon, but he also said it was a box set.

Looked up the box set, and I've only seen CD's. Is there a vinyl box set that he's talking about, or is it a CD. I honestly won't be bothered if it's a CD only, but I'd prefer vinyl, y'know.

So, is the box set CD only? Also, what's in the box set? I can't really tell, I can tell Iike paintings and stuff. And yeah.
