While games on the PS3 have supported 3D for a little while now, Sony hadn’t added 3D support for Blu-ray movies. This is set to change on the 21st of September though, when Sony will release a new firmware update for the PlayStation 3. Firmware 3.50 will allow all PS3s worldwide (38 million of them) to play Blu-ray movies in 3D, as long as you have a 3D TV of course. Other features should be included in the update as well but, we’ll have to wait until the update is released to find out what.
