The Metroid franchise is very important for Nintendo and a new game in the franchise is definitely something Nintendo wants in the future.
Miyamoto said that Retro Studios is one of the top candidates to work on a new game in the franchise.
This was said during an interview with the Official Nintendo Magazine:
“I definitely think it’s a franchise that we value and we certainly want to see what we can do with it in the future,” he said. “And, obviously, Retro is a very high priority in terms of the potential team that would be considered for working on a Metroid game.”
