The lights are on
Nintendo is usually secretive about almost anything that comes from their in-house departments, being games or consoles. It usually bothers the hell out of me, because Nintendo news is the first thing I usually look for. I doubt GDC will have anything new, and will probably only show what has been shown at CES (which was the same thing shown at last year's E3). If you want any mind-blowing information, you're better off waiting for E3.
