I remember something from CES where someone was showing off tech for a 3D TV without glasses, but the problem with it was that you had to sit within a specific area to see the 3D, which, of course, wouldn't be a problem with the DS, because everyone would be holding it in nearly the same place. If it's not too expensive, then thumbs up to Nintendo. For some reason I think 3D used on a handheld would be used more creatively (and less just to show off) than on a console. On a console I think 3D would just become more of a pissing contest for graphics, whereas a handheld is more limited, so it's not just going to be about the graphics. Just an idea, anyway.
