He is in charge, but not the only one in the process of making it.
Nintendo has not stopped making Pikmin games: Shigeru Miyamoto has confirmed several times that Pikmin 3 is in the works. They have been in the process of creating the third game for a while.
Shigeru Miyamoto, creator of the Pikmin series, announced at E3 2011 that the game would be shifted to the Wii U, Nintendo's upcoming console.
It was created by Shigeru Miyamoto.
Mr. Miyamoto has confirmed both. Nothing else has been said other than they will be in the game, though.
As of July 8, 2011, there is no certain release date for Pikmin 3. It has been confirmed several times in the past that Pikmin 3 was in development for the Wii, but according to Shigeru Miyamoto, it now appears that it could be made for the Wii U, which is scheduled to be released in the spring of 2012 at the very earliest. On June 8th, 2011, a day after Nintendo's presetation at E3, Shigeru Miyamoto stated the following: "We really did want to release Pikmin this year in honor of [the series' 10-year] celebration. Earlier, someone asked if we're working on any other Wii games after Skyward Sword. Well, Pikmin was a Wii game we were working on. However, as we've been working on Wii U hardware and I've been looking at those high-definition graphics and that beautiful controller, I've been getting the feeling I wanted to see Pikmin there instead."
Pikmin 3 is a real time strategy game, and will be the third game in the Pikmin series. So far, all we know is Olimar and Louie are gone, which Mr. Miyamoto said the reason was a secret, suggesting the story might have something to do with that, and then we have the new Rock pikmin, the five old pikmin, and the confirmed but unknown new pikmin later in the game. An unconfirmed pink pikmin can be seen briefly in the beginning and end of the trailer.
Honestly I don't think Pikmin 2 is going to come out for the Wii. It is near the death of the console and Miyamoto-son already said hinted at Pikmin 3 for the Wii U. I just don't see it happening.
Yes, they have confirmed the making of Pikmin 3 on the wii u in 2012.
There will not be a Pikmin released for the DS. Pikmin and Pikmin 2 were originally released by Nintendo exclusively for their GameCube console, however both games have been upgraded with the 'New Play Control!' to enable them to be played on the Nintendo Wii. Nintendo has confirmed they are working on Pikmin 3 for the Wii which is coming out somewhere near the end of 2009 or beginning of 2010. There will definitely not be a Pikmin game for the Nintendo DS. There is only one planned release of Pikmin, and that is Pikmin 3 coming out for the Wii. No other announcements have been made, but many have stated that there will be no Pikmin DS. More details on the 'New Play Control!' and its release dates are shown on the related link.
Although it's an unconfirmed pikmin, it will most likely to be nature
Pikmin 3 is only made for Wii U.
Nintendo released Pikmin 3 in Japan on July 13, 2013.
