Eight long months after the launch of the Xbox One and PS4, both Microsoft and Sony have finally announced support for playback of 3D Blu-rays. I'm certainly not going to turn my nose up at the addition of new features, but it does make me wonder what took so long for these updates to surface. The PS3 has had 3D Blu-ray support since 2010, and it works perfectly fine on that aging hardware. So, what's the hold-up on the current generation?
