I don't think they should make new pikmin for the next game, 5 is too much. They should add some new gameplay mechanics (just a little tweek, don't get any smart ideas, Nintendo).
Multiplayer was awesome, stick with it. Make Pikmin scary, as in the sense that you don't want to go into an area unless you've got the balls to do it. The world is self-explanatory, make it good, interesting, and dangerous.
