It could be the analogue of the Mac Mini compared to the iMac, it would fill a niche for those that want the Apple TV experience but already have a new fancy screen. So maybe the full TV would take over the AppleTV name and the little box would be dubbed the "AppleTV Nano". I bet it could sell well as an entry-level option if there are a range of products (and of course apps) in the ecosystem. As it is now it is an oddity.
