I can't believe how much Nintendo are driving this hype machine. It depresses me how naive consumers (and the media are).
Some people are even claiming that Nintendo "stole the show", despite knowing nothing about the 3DS, how it magically creates 3D without glasses. The answer is, it doesn't it's a very crude form of 3D using Parallax Barrier display.
However we all know know how it works. You build massive amounts of hype based purely on lies, rumours and half truths, ensure your product is drip feed to stores to create an illusion of crazy demand, and you will be sure to have queues of clueless idiots standing outside stores at midnight and fighting other clueless idiots to get ahold of one.
I guarantee right now, that the 3D won't come anywhere close to what active shutter glasses on a proper 3D system will deliver.
I also guarantee the stories leaked (by Nintendo) to the press about the 3DS having graphics that match the PS3 and Xbox360 are totally laughable....
