Kotaku reports on the New Xbox Experience, which does away with the Blade interface, and replaces with a remote-control type UI with cover-flow-like browsability. We'll have to see what the reception will be for this. Xbox are integrating Netflix soon, and may be hoping to simplify the experience for a wider audience. I found the Blade UI to be pretty interesting the few times I got to use it.
