Like everone else you will get it when it becomes available.
This not a leased line type service whereby BT or other suppliers will give you dates and accept loads of money in exchange.
As long as you are in the roll out plan (use BT ADSL Checker with the telephone number) then you will get it when the date finally stops being pushed forward in 3 month increments.
You certainly cannot make business plans around the delivery of this service.
