Pikmin 3 may be a Wii or DS game.
In 2003 Miyamoto said in an interview he already had the basic premise for Pikmin 3[1]
Cubed 3 news ran an April fools joke in 2006 stating that Pikmin 3 would be a launch title for the Revolution (Wii)[2]
Later in April Spong news asserted that according to its press contacts Pikmin 3 would appear on the Wii at some point (probably some time after the launch) [3]

In the original Pikmin news articles, it was hinted at that Pikmin may be a trilogy.
A Possible Pikmin 3
In an interview with Shigeru Miyamoto, the interviewer asked if he planned to do anything with Pikmin in the following article:[5]
July 12, 2007 - Every time we chat with Nintendo's famous producer, Shigeru Miyamoto, we bring up at least one franchise we'd like to see remade for the company's current-generation console. It used to be Metroid. Then it was Kid Icarus. And most recently, it's become Pikmin. When quizzed on the subject, Miyamoto all but revealed that another Pikmin was in development for Wii.
"I certainly don't think we've seen the last of Pikmin," he said. "I definitely would like to do something with them, and I think the Wii interface in particular is very well suited to that franchise."
Of course, he did not divulge any further specifics, but it seems to be a safe bet that we'll see the return of the Pikmin franchise on Wii at some point in the future.
Though he didn't fully announce it, it is safe to assume that a Pikmin 3 will appear on the Wii. Whether the game is in development or not is unknown.
On the 18th of April, 2008, Shigeru Miyamoto revealed in an interview on the topic of Wii Fit that he desired to continue with the Pikmin series in the following article:[6]
As for what the developer would like to work on next, Miyamoto said he's looking forward to working on the Wii some more. He also reiterated his desire to make another entry in the Pikmin series of action strategy games.

The appearance of Olimar in Super Smash Bros. Brawl for the Wii may increase the likelihood of a third Pikmin game being released.
