Easy - Everything connects to Thanos, and the impending release of Avengers 2 come 2015.
It's really speculation now at this point, but given the fact that surprises and confirmations are due when San Diego Comic Con hits this July, we just have to wait and see. Still, reports suggest Marvel has gotten domain names related to GotG, so that's a sign and positive feel we may get this flick. For more on the buzz surrounding Guardians, visit the source post at Latino Review and Comic Vine.
If this is true, I'm hoping Rocket Raccoon or Nova is in this movie.
