RE: Kids and 3D
My kids (4,6,7) absolutely LOVE 3D stuff and have asked repeatedly why they can't watch stuff at home in 3D.
Sony is just back peddling to its investors as to why Nintendo has once again beaten them to the next requirement in gaming.
Also, considering Sony's push for 3D TVs using the active shutter system (which I despise), Nintendo is one-upping the idea with the far more realistic approach of no glasses.
