I'm told there are up to 60 FPP cadets who have been delayed into next year, and that they will likely have priority over any DEP entrants as the company have a 'duty of fairness' to them. In reality, the training department might have something to say about that of course.
I was also told that there would be a total intake of around 150 crew in 2018, inc FPP, suggesting ~90 from the hold pool, but potentially later on in the year if the FPP guys/gals are starting first. Suggestion was that hold pool expiry dates might be extended again.
All rumours of course - I was told this by a friend in the company who spoke to someone in pilot resourcing, but it seems, per SOP, there isn't really a definitive plan at the moment!
