We caught a far off version of this teaser (which was recorded in the audience by someone yesterday), but now a much clearer and bigger recording has found its way online! It doesn't appear as if Marvel will be releasing this officially, but I wouldn't be at all surprised to see it included on the Guardians of the Galaxy Blu-ray this November. Fans have long speculated about the identity of the Infinity Stones, but now we know which artefacts from the Marvel Cinematic Universe are indeed part of Thanos' gauntlet. How he gets his hands on them and it remains to be seen...
