Of course, this is exciting news – but there is certainly a noticeable lack of specificity that James Gunn includes when talking about the future.
Gunn has talked a lot about not only Guardians of the Galaxy Vol. 3 being his last feature for the franchise, but also about big future plans for the cosmic side of the Marvel Cinematic Universe.
It would be nice if the phrase “coming sagas” simply connected the Rocket backstory information to the writer/director’s Guardians of the Galaxy Vol. 3, but the truth is a lot less simple than that.
In fact, there are a lot of people who are betting on seeing a Rocket & Groot spin-off at some point during Phase 4 and beyond, and that project would certainly be the best place to start diving into the history of the talking Raccoon.
