James Gunn has revealed that the Infinity Stones will not make an appearance in Guardians of the Galaxy Vol. 2.
Given that the Power Stone – the fourth discovered in the MCU – was a major part of the first film, it makes sense that Gunn would choose not to include the Stones in the follow-up.
Answering a question put to him on his Facebook page, Gunn confirmed;
Set to the backdrop of ‘Awesome Mixtape #2,’ Marvel’s Guardians of the Galaxy Vol. 2 continues the team’s adventures as they traverse the outer reaches of the cosmos. The Guardians must fight to keep their newfound family together as they unravel the mysteries of Peter Quill’s true parentage. Old foes become new allies and fan-favorite characters from the classic comics will come to our heroes’ aid as the Marvel cinematic universe continues to expand.
Guardians of the Galaxy Vol.2 will be released on 5 May 2017.
