Well, you’re about to get your back-scratchers back, because it will. You won’t need to do anything to their consoles, either – all you’ll need is a 3D-compatible display.
It might seem odd that it’s so easy, but it’ll work because the 3D spec is only an extension to the existing format. So if you don’t have the 3D display, the new discs will still play in good old 2D.
And when you do finally upgrade to something that can display the discs properly, you’ll find that they play in glorious 1080p Full HD. Lovely!
