if you go to wikipedia.com and type in little mermaid III, it says that there will ba anohter sequel slated for 2007 and that the new little mermaid Platinum DVD which comes out on October 3rd will have a sneek peek of the third movie
sharethat's correct, the teaser trailer for 3 ( mostly clips form the original ) and the music sneak peek are already around youtube and will be on the platinum edition dvd. there are about squat info on what it'll be about except that in the music number shown ariel is a mermaid so it may even be a prequel to the original.
we shall see...
