According to the BA calendar they are planning on running the Prospects Camp again on July 19 to 21.
I would guess that BA havent mentioned anything about it as they are in the process of getting the event certified. The NCAA event certification process is a long and slow process, applications really werent looked at until last month. The NCAA has put in a new online system and new requirements for event operators so its probably slower than usual.
Theres around 40 events certified for the US summer so far, this is a far cry from the couple of hundred events that run every July.

BA is hamstrung, they cant say the event is certified until the certification is approved which they have no control over.
