User blog comment:ADour/First official image of and synopsis for Guardians of the Galaxy!/@comment-1895174-20140101043450/@comment-3215006-20140102163146

Feige has said that the Tesseract is the Space Stone. I think I read somewhere that the Aether is the Power Stone, though I'm not sure. And for the Orb, which is likely what it'll actually be called (but I kind of hope not), has also been confirmed as an Infinity Stone by Feige for anyone who was unsure, though no hint as to which stone. My only guess would be the Soul Stone/Gem based on the relationship between it and Adam Warlock in the comics and his membership to the Guardians.

I also didn't think "Raccoon" was actually part of his name, but I agree with @ADour that it was left out to avoid redundancy.
