flOw is a downloadable game designed for the PS3, but it was originally in consideration for the Wii.  Developer ‘That Game Company’ was in talks with both Sony and Nintendo about the game.  They ended up going with Sony, but they expressed that they would be willing to work with Nintendo in the future:

FlOw creator Jenova Chen chimed in, saying “in the end, we are game makers and not console makers,” expressing his satisfaction working with Nintendo on other projects. That Game Company did not rule out working on the Wii in the future.

flOw looked like a cool, artistic title similar to Electroplankton—so I’m very interested to see something like it eventually come to the Wii.
