The excitement over the DSi 3D tech demo is understandable, but I'd sound a note of caution to those demanding games immediately. I don't want to sound like a grumpy Gus, but the eye tracking technology will almost certainly only be workable in an well-lit environment - if the DSi's tiny wee camera can't see your eyes, it's just not going to work.
