BA will take from CTC but they are not taking any current cadets as far as I'm aware. They are taking 30 per year from CTC (and the same from OAA and FTE) and all of them will be 'tagged' by BA from day 1 following a rigorous selection process. Anyone who has already commenced training will not be eligible for BA, only those that BA take under the FPP. So BA taking cadets helps no-one that has already started training.
This is not correct. As it will take a couple of years for the FPP cadets to go through the system BA will take on current Wings Cadets in the period in between. Current estimates are that this will not need to take place until mid 2012.
