Boscombe Down

What is going on at Boscombe Down?
I have heard that several of the units currently in seperate hangars are all moving into the large green hangar leaving at least 2 hangars (rotary wing and another) free for other units to move in to.
Who could these other units be, is Boscombe Down becoming more of a ‘standard’ RAF air base now over the experimental establishment it once was?
