Re: If the Guauntlet fits, you must admit .... it's time for Thanos!
Personally, I see Thanos having a major role causing the events in GotG which causes them to either come to Earth or send word to Earth that Thanos is now coming for them in Avengers 2, which sets up the connection between the two films that Gunn just confirmed there will be.
Sidenote: he also just confirmed there's no Iron Man in GotG. Now this could be a ruse but my guess is he's telling the truth.
1) Man of Steel 2) Thor 2 3) The Wolverine 4) Pacific Rim 5) Iron Man 3 6) Oblivion 7) Mortal Instruments: City of Bones 8) Ender's Game 9) Beautiful Creatures 10) After Earth
