Talked to recruiters today. They said an email will go out shortly to give a phase 2 update, with forecasted class dates for Jan and Feb. Jan 8th class almost full and next class is Jan 22nd. The pilot hiring committee will be meeting soon and reviewing those with all PRIA info complete. Those who get the thumbs up from Sept/Oct/Nov sessions would be in Jan-Feb classes. Only bad news is those planned for the Jan 22nd class and beyond may have to move their applications over to the new system by "re-applying" (just so that they can be cleared quicker, because they said the new system moves faster for background clearing).
Advice - if your prior employers are dragging their feet in completing PRIA, you should do whatever you can to get them to speed up - as you'll lose seniority fast. Recruitment team said class sizes are planned 20-30 in Jan/Feb (two classes per month), so every class you miss, means you're losing seniority.
