A battle for the future of 3D cinema is brewing between Sony and Theaters over the cost of 3D Glasses.  Previously provided by Sony, now they want individual theater guests to buy their own sets of glasses, which NATO (National Association of Theater Owners) says really translates to increases deployment costs fot theaters.

In its statement, NATO said press reports indicate that Sony wants audience members to buy their own glasses, but in reality, the studio wants to move the expense of providing glasses off their own balance sheets and doesnt particularly care if the cost is borne by theater owners or ticket buyers.
