If there was one thing that was lacking from Nintendo's E3 that many was hoping for news on was Pikmin 4 which was announced back in 2015. Sadly it was MIA but Nintendo did say this:
In an interview, Miyamoto said that, even though he can't share any new details about the game, Pikmin 4 is "progressing." In a separate statement, Nintendo followed up on Miyamoto's comments, confirming "that Pikmin 4 is in development but that is all we can confirm at present."
