Wow, that sucks and is quite surprising. That would turn a lot of people off if they know that they have to keep popping in new batteries. I think those who come up with a charging dock type approach (like the PS3/XBOX controller chargers) will probably be more popular with consumers. It’s one thing to remember to just leave the glasses on the dock when not in use, but it is quite something else to go hunting for batteries and to always keep a fresh stock around for the glasses.

I wonder if there is rechargeable battery.

I do think that documentaries and 3D Gaming will look amazing and will help push this technology. Same goes for well made 3D movies (and not the cheap 2D-> 3D conversions). As for sports, I think there is good potential but it will probably benefit some sports more than others. For many sports like soccer where you are looking at a zoomed out view, there is a very large focal depth and it really prevents a “pop” when viewing the content.
