Spore's arrival on the Wii has been stretched out over such a protracted period of time it would make evolution itself blush. Will Wright first confirmed the project way, way back in October 2007; optimistically, we placed the game in a list of titles to look out for in 2008.
Nevertheless, let's say it again: Spore is coming to Wii. Yay! This time, to make things feel extra official and important, EA made the announcement, revealing that Spore Hero, a game built from the ground up for the Wii, would focus on "creativity and evolution." And that's really all we know for now, aside from the fact that the game will release this fall.
Considering it's taken EA the best part of fifteen months to announce the thing, and given the first game's reputation, we wouldn't be amazed to see some slippage. One to watch out for in our "Games for 2010" list, perhaps.
