Radio isn't really that necessary. In game music I wouldn't mind. Definately cross/in-game chatrooms. More work put into the Life With Playstation program(a bunch more cities, 7-day forcast, more detailed and area specific news etc.) Web browsing wilst in a chat room(only if not in game). Faster download speeds if they can fix it. And possibly sharing videos you have and watching it in a chat(this sounds something like they might plan for Home but who knows).
