Don't expect to see that superhero movie in the format without glasses on the big screen, though. Given how long it took (and is still taking) for theaters to convert to digital 3D-capable screens, I don't see the industry going too crazy for any further advances requiring more costly equipment upgrades. Not anytime soon. So the big issue here is that 3D TVs will keep improving and adapting to consumer satisfaction while cinemas will have to deal with what they've recently invested in for a long time. And people will have another reason to stay home: the 3D in their living room will be better and more comfortable.
Despite some spin made by blogs like Superhero Hype and Splash Page, I have to note that there's no real connection made by Sony or by AP's report on this topic between the Spider-Man reboot and its potential to be available in glasses-free 3D. By the time the Marc Webb-directed film hits home video 3D DVDs and Blu-rays will be fairly common, so it's not a big deal or surprising that this 3D movie would also be available for 3D home video formats. However, it would behoove Sony to mark the film's home video release as a temporal aim for its tech plans due to it being a Sony title. Yet they should also worry that announcing such a goal too soon might have many moviegoers avoiding the theatrical version in order to wait for the more convenient option.
Will you be less interested in the 3D theatrical experience once you can have that experience at home? Especially when the need for glasses is eliminated?
