On Videogamesblogger.com there's some quotes from Spores creator Will Wright that seem to confirm that - at the very least - EA and Wright himself and looking into brining Spore to consoles as well as PC. Deffinitley Worth a quick read.

"It will probably take very different forms depending on the platforms. We might even pull out parts of the game – so you might be playing part of the game on a handheld platform, you might be playing the entire game but maybe more avatar-based on a console. The consoles are getting kind of different now – I think there's a really interesting distinction between the Wii and the Xbox 360 and PS3. Something like the Wii offers a lot of interesting creative opportunities for the editors, with the controller."
