Yeah, Turing is a language they teach in high schools in Ontario. Game programming mostly uses C++ currently. C# is beginning to get some reception because of tools like XNA.
I have no idea what Nintendo is going to use. I've heard they're going to add some game dev tools to WiiWare next year or put independent games on it at least. They haven't made it very clear in their press releases what exactly they're talking about. Some think they're going to do something to compete with XNA.
