I doubt it. Firstly, a port from Wii to PS3 would be a port up. The game would need significantly more detail (and features) to justify that extra power being used. This would also take a fair bit of money.
Secondly, the Wiimote comes with every Wii, which means that every single Wii will be able to use those motion controls. Sony motion control will require a Playstation Eye AND a PS3Mote, which could easily add on an extra $100 together. The userbase would be significantly smaller.
Thirdly, the PS3 and Wii motion sensing is very different. While the Wii motion sensing is picked up by a sensor bar, and uses two dimensions, the PS3 motion sensing is picked up by a camera, and uses THREE dimensions. You can move forwards and backwards in the game. And it has a coloured orb on the end!
So in short, no, this wouldn't happen.
