You know Datel? The company that makes all the Action Replay stuff? Well they've announced today that they are going to be releasing an Xbox 360 to PC transfer kit.
It's essentially a memory card for the 360 with a usb connection that hooks up to your computer. It's designed for transferring save games, maps, etc between friends.
It will be available very soon and retail for 14.95.
Sounds like a good deal if you ask me.
