"If it comes it comes; when it comes, it comes. I'm not a tech guy, particularly. I'm a design, story, character guy. I think most of the problems we have to solve are creative ones, not technical ones. Obviously we make software, so there's always a technical element to what we do, but I will make games that do whatever I want them to do at the end of the day, and I will use whatever technology [is] available." - Warren Spector
I believe what Spector has to say in this case. He made Epic Mickey for the Wii, and the sequel is seeing lead development on Wii as well. You work to the best abilities on a platform, and creativity is where the real ironing out has to be done.
