Planet Of The Dead Transmission Date

Planet of the Dead is to be transmitted on Easter Sunday, which throws my prediction of Saturday out by 24hours! This means Doctor Who isn't going up against Primeval, and Robin Hood doesn't need to move up!
The BBCs Easter Egg to us will officially be the 200th story! There is no transmission time as of yet, but you can bet its on around 7pm :) It will be the first Doctor Who story to be transmitted in HD!
