Of course he doesn't have the keys, lol, we already know that. He has been claiming that he is Satoshi even prior to the case and I'm sure if the court proves that he is not Satoshi, he will continue his assertion of the truth. And that what a pathological liar like Craig is, even if we have all the evidence plaster around his face, in his mind, he is Satoshi.
You are right, since the beginning he has no evidence he knows it but continue to have an interview and get a media mileage. For instance that he has a key, he should allow media to cover him live and transfer even 0.00001000 BTC to prove he is the owner but he did not. I think this is case closed already.
