SERIES 6 IS GOING TO BE SPLIT IN HALF AND PARTLY AIR IN SPRING AND PARTLY IN AUTUMN, WAH.
The split transmission is the result of a request from Steven Moffat to write a new Doctor Who story arc which involves a big plot twist in the middle of the series. By splitting the series Moffat plans to give viewers one of the most exciting Doctor Who cliffhangers and plot twists ever, leaving them waiting, on the edge of their seats, until the autumn to find out what happens.
Massive plot twist, eh? Unannounced regeneration, perhaps? I FUCKING WELL HOPE NOT.
