Wireless Keypad shown off in new video
Thankfully, Sony have put together this rather swish video showing you how it all comes together.
As well as the keypad, Sony have also detailed a new AC Adaptor that can charge two peripherals at once without having to use the PS3 USB slots. In their example (below) you can charge the PS3 controller (with the keypad attached) and their new Bluetooth Headset, although you can use this with any mini-USB connected device including the PSP.
Looks like the Holiday Wish List might need to grow a little!
