I remember back in the day, we used to have loads of friends round, crowded around the original playstation, playing 4 player games (or even up to 8 player Micromachines by sharing the controllers between 2). good times had by all!
this "advancement" in techology is only going to let 2 people play the game at once. and anyone else in the room isn't going to be able to see a thing that's isn't at best horrible blurred, and at worst a composite of two entirely different scenes overlaid on each other.
it's a step back in multiplayer enjoyment, because half the enjoyment is for those in the room not currently playing, but waiting for their turn to do better.
but then, it's a moot point isn't it? there's feck all decent multiplayer games out at the moment that allow 2 or more players on a single machine. they're all geared at multiplayer over the internet
