Yep that`s correct, I believe he has some contact with an ancient old moon bear in his very first months, but since that, he`s all on his own in the former spectacled bear enclosure.
In the wild, cubs stay with their mother for much longer than the period Knut was handraised for. Its unsurprising that when seperated from his carers- because he was already growing big and dangerous- he gave continual 'lost' distress vocalisations, as in the wild he'd still be with his mother/sibling at that stage, or if separated trying to find them again..
However I don't see why Knut can't be integrated with other Polar Bears successfully in the future.
Its interesting how the massive interest level surrounding this cub was similar to the hysteria produced by London's cub 'Brumas' in the early 1950's. Interest levels in her also diminished rapidly as she grew out of her 'cute' baby stage and after a year or so only the name 'Brumas' remained famous. As an adult bear she had no special appeal or interest for visitors at all.
