12 million is probably about right for the final BARB figures, with HD added in, however the overnights are 10.4 million, so the thread title is wrong. Don't think the Sun's predicitions of ratings are ever a good bet.
eta: someone in the part 1 ratings thread was predicting Corrie would batter DW, well Corrie got almost a million viewers less, in actual fact.
eta again: HD figures of 389,000, which means actual overnights of 10.79 million
