Everyone does realize that current 3D content will be compatible with future full-sized autostereoscopic displays right?
Meaning, your 3D BD movies, your 3D PS3 games, etc. will still work on any autostereoscopic HDTV with an HDMI 1.4 interface.
They just don't make large format autostereoscopic displays currently because the limited viewing angle of the 3D effect in today's autostereoscopic displays (such as the Sharp display being used in the Nintendo 3DS), as well as price. There's no point in having a big screen glassless 3D display if the effect can only be seen by the viewer sitting directly perpendicular to and centered in front of the HDTV.
40" autostereoscopic displays will also cost quite a bit more than the glasses based models currently available, which can bought today for well under $2,000. Just this week I saw an ad for a 46" Samsung 3D plasma HDTV for under $1,300.
