Sharp-eyed fellas at Oni Central have noticed that Rockstar Games now has an Oni site up. It's got a new movie that shows (among other things) cutscenes and the user interface. The official site launch won't be until December, but it's definitely worth a look right now. (You need Flash, by the way.)
Addendum - In the event that you're looking to bypass the Flash to see the new movie, Mumbles passed along a link that'll take you right to it.
