They said at end of last series... end of summer... so that would make it Sept/ October time for UK.. then the lead up to the Xmas special...

I tell my wife who has only just got into this great program that you have to go right back to episode #1 of the new series to fully understand all the little twists and turns that occur...... Dr Who is so well written these days.. surely a movie will follow at some point ( made by BBC i hope not friggin USA)
