We all expected most of the new interface and features on Apple announced for the new generation of the Apple TV to find their way down the previous generation, and just as with iOS 5.1 for the iPad and the , Apple isn't wasting any time. We hear that the update should be available today, bringing the new interface, movie re-downloading, and direct Netflix signup to current models. Of course, that won't mean that current models will be able to display 1080p content, but beyond that small niggle it appears that the previous generation will still be functionally identical with the new model.
The update hasn't appeared for us yet, but we'll update as soon as it does. In the meantime, don't miss our hands-on video with the new interface!
Update: Our 2nd-generation Apple TV just popped up a download for the new software, go get it!
