Nintendo's moving into the 3D realm with their announcement
of the Nintendo 3DS
portable gaming system. The system's set to deliver 3D pictures without the need for glasses and should be out by the end of the fiscal year of March 2011.
No other details were said but this will probably be a hot item for E3 as that's when Nintendo's offering up additional details. I've seen some of the the displays at CES where they tried to do 3D without glasses and the quality was pretty eh. I've read that these things work a lot better in smaller displays and the follow up to the DS would be a great candidate.
-Update- It looks like I was correct in my assumption as the NY Times has confirmation
that the 3DS
will be playable at E3.
