Money is on 2016, albeit there was a hastily withdrawn note recently that had 2017 on it. There was talk of 2015 for new entrants only (like they did for AFPS 05) but not seen anything with that written on it for a while. We are told that a bunch of information will be out by March with the calculator going live for regular folk the following month.
In truth the rumour mill has as much information in it as the formal stuff. The 'Senior Leadership Team' got their lines to take in the last couple of weeks.
