I consider the Pikmin franchise dead right now.
Pikmin 3 will end up with less than 200K in the Japanese region, well below the 475K units of P2 and very disappointing for a game that had several years in development. Hardly, Nintendo will invest in Pikmin 4 in the near future - unseless P3 has excellent sales in Western markets, I believe that Nintendo may invest in the franchise, which I doubt, given the small sales of P1 and P2 in the West.
