Technically we shouldn't even be able to see the fifth chapter; they're opening Chamber of Secrets in three separate installments: 1-4 were made available on either the first or second of August. They're still working on 5-11, it's a lot to get done so we ought to try and be patient (I'm not boding too well with patience), but the artists just finished the artwork for Snape's office, and they were working on it for a while now, so it should be soon. Some fans speculated that it would be done on the first of September, as that's the day most of the action in chapter 5 takes place, but who knows? It's definitely going to be before 2090, at any rate.
