So how are you going to watch 3D TV or 3D Blu-ray movies on the 3DS? exactly, you wont. Not mainstream.
I feel like we're just arguing over the definition of "mainstream". Does a device really need to include all major media formats to be considered as such? My understanding (and the definition from m-w.com) is that mainstream means "a prevailing current or direction of activity or influence". My point is that glasses-less 3D is obviously not "prevailing" on big screens yet (which is also exactly what you're saying), but we expect Nintendo to make the technology extremely popular throughout the world, with or without Blu-ray or 3D movies. I don't understand why those things are required for something to be considered "mainstream". The Wii doesn't even support HD, but it definitely made motion a mainstream form of control.
