Using accelerometer for 3D would give us the same results as this game on the DSi using camera tracking:
<object width="480" height="385"><param name="movie" value="http://www.youtube.com/v/p3lDoVwEmts&hl=pt_PT&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/p3lDoVwEmts&hl=pt_PT&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>
Why launch a portable with a different name, more graphics, and more pricey, that at the end the "3D" is the same as seen in that video?
Why does it have the Sharp 3D LCD screen then?
Also Nintendo said "3D without glasses" so it means its stereoscopic images, and those videos only shows successive single frames, otherwise you would need glasses to see the 3D effect.
Nintendo probably is talking here about the 3D you see in avatar, but you won't need glasses.
