Many people have been clamoring for a sequel to Pikmin 3. Since Nintendo’s time with livestreams and tons of upcoming game information at E3, Pikmin 4 has not made an appearance.
Pikmin developer Shigeru Miyamoto has a reason as to why this is:
“I’ve been told not to share anything about this from PR…but I can tell you it is progressing.” – Shigeru Miyamoto
Even though this is not the news Pikmin fans were hoping for during E3 2017, it sounds like the long awaited sequel to this series is at least in the initial stages of development.
