Excerpt of interview with EA:
“I certainly think that the Wii controller has a lot of exciting potential. If I were to develop something on the Wii… I might consider using the controller in a conventional way…For example, use the controller as a sword in an RPG, but only for the final climax of finishing off the final boss character. I believe that being selective in where the function is used would give players a sense of accomplishment.”
“I think Wii is a great potential console for SimCity as well, as it is a franchise that can expand on gameplay, and not rely solely on graphic quality. It could also appeal to families by having features that teach children about building a city, or make full use of the network connectivity.”
