Some points which tend to contradict the nonsense posted by JMC-MAN and others:
1. They have at least 20 people in the office at Luton, and growing.
2. Route proving flight seems to be confirmed.
3. the simulators are booked for courses, with people on courses now.
I think they are being very smart in not releasing information into the public domain, in fact you could say it is very clever tactics not to release information until the day before launch even.
