Sony unveils a slimmer, smaller PlayStation

Sony is introducing a smaller, slimmer and lighter version of its PlayStation 3 console ahead of the Christmas rush as it gears up for growing competition in games from smartphones.

The announcement from the Japanese electronics and entertainment firm came a day ahead of the annual Tokyo Game Show, where gamemakers show their wares.

The timing also coincides with tomorrow’s launch of the iPhone 5, which is drawing long queues at some retailers.
