The forecast is due in the new year. It is based on expected attrition vs establishment levels required for the new flying program. The flying program is influenced by this so-called 'economic crisis', and it will be lower = less flights = less aircraft required = less pilots required. Aircraft requirements will be managed as documented in other threads and by the media last week. Pilot numbers get managed by assigning leave, reducing flying, adjusted promotions and transfers, and a reduction in recruitment.
Exactly what these recruitment figures will be won't be known till the forecast actually comes out.
