Guardians of the Galaxy - A new Avengers?

A couple days ago Chris Pratt premiered the first trailer for Marvel's new movie Guardians of the Galaxy on Jimmy Kimmel's show in the US. I know absolutely nothing about the source material on this, but I do know that it ties into the after-credits scene of Thor due to The Collector getting his hands on an Infinity Stone from the Asgardians which is what Chris Pratt's Star Lord is after in this. It also connects with the post-credit scene reveal of Thanos in Avengers Assemble due to Karen Gillan's Nebula being an agent of Thanos and Gamora being his adopted daughter, but I'm not sure what it will lead to..

With characters such as Groot, Nebula and Rocket looking incredible, the film will be gorgeous and hopefully as funny as the trailer is. Even though I know nothing of the original Guardians of the Galaxy comics, I do know that this looks amazing and after that trailer I'm more than excited for the August 1st release.
