You know what's absolutely useless? A video of Wipeout HD being played in 3D, with some schmuck wearing 3D glasses and babbling on about how much fun he's having. Well, that schmuck is this Engadget editor, the video can be found after the break, and we've gotta say: we loved it. Especially for something like Wipeout HD, whose neon-infused tracks make for an almost too convenient example of rapidly approaching vanishing points, we'd say 3D could really be a quasi-"killer app" for consoles going forward -- especially if those fancy new motion controllers don't catch on for Microsoft and Sony. In many ways, 3D just seems to make more sense in a video game than for a movie, and the whole problem of finding content to deliver in the format has already been solved: a software update for the PS3 sometime in 2010 will enable it to provide a 3D viewing experience to "all" existing games on the system. We're sure there will be some exceptions, but it sounds very promising. The console itself pumps out a quite regular signal over HDMI, which the TV syncs up with your 3D glasses. A 200Hz TV, for instance, alternates 1080p frames, with 100Hz for each eye. Of course, you'll need a brand new TV, but at least it won't be restricted to just Sony televisions. Start saving those pennies!
