I saw a BBC article this morning about BT extending its coverage in Scotland but so far BT itself has not released, either to us or in public, any list of "new" exchange upgrades beyond what has already been announced. I've shot off an email to find out what's going on as we usually know in advance about these things.
The list you link includes many that exist already and may represent date shifts / delays.
I think BT have reissued the list and added new exhanges to the list I remember someone asking about a date for Sudbury on this or another forum and thats now on the list. There seems to be quite a few new exchanges in Norfolk & Suffolk that I a cannot recollect being their before
