microsoft has a technology in development generates 3d without needing glasses at all.
3d Without glasses
"Microsoft's prototype display can deliver 3-D video to two viewers at the same time (one video for each individual eye), regardless of where they are positioned. It can also shows ordinary 2-D video to up to four people simultaneously (one video for each person). The 3-D display uses a camera to track viewers so that it knows where to steer light toward them. The lens is also thin, which means it could be incorporated into a standard liquid crystal display"
It needs monitors with at least 240Hz (120Hz per viewer). With enough Hz, lots of things are possible with this tech. Such a display could show a standard 2d view to one person (using 60Hz), and other people could see specific a 2d display for each extra 60Hz. (or a 3d view for each 120hz).
Other companies are also working on glasses-free displays, so there's still plenty of innovation and development to come before we have a standard.
