That was sure a mouthful of '3' but a second PS4 video has made its way to the web hinting at some exciting 3D PS3 action.  The game in question is Modern Warfare 2, probably the most popular PS3 title, being tested on some human guinea pig with a taste of the third dimension.  Sure, the second video in the 'series' isn't quite as Blair Witch-y as the first, but if both are actually Sony's doing, it looks like the PS4 references are actually hinting at the PS3's future in 3D.  Check it out, dream of some MW2 in 3D, and let us know if you think Sony's going 3D at E3.
