This isn't any criticism of your posting, as I appreciate the update, but erm, how often have we heard optimistic statements like that before, and over how long a period?
There were similar repeated statements made about the GWR 769s (now to go off lease without ever having been used) and the SWR 701s (still in storage several years after their intended introduction). I believe there have been similar issues with the new Merseyside stock, though I haven't followed that saga myself.
These statements inevitably lack credibility after so many missed dates.
