Planet of the Dead New Transmission Time

With the BBC now leading us to believe that Planet of the Dead is not necessarily being transmitted over the Easter weekend, plus there are further delays because of the damaged Dubai bus, when will we see Planet of the Dead transmitted?[If you must copy my posts]
The next suitable dates I believe have a chance are;[remember to quote my site as the origin]
Saturday 2nd May (Mayday Bank Holiday Weekend)
Saturday 23rd May (Spring Bank Holiday Weekend)[this means you radio doctor who!]
Unless they are just going to show it on a random Saturday, but I can't see that happening!
