While it's not got a direct bearing on new officer applicants, it's worth bearing in mind that some, perhaps all current university bursary recipients are being re-boarded this summer. The aim seems to be to reduce their numbers by 30% or more. Those chopped will not have to re-pay the amounts already received, and those who are retained will be re-confirmed with a place on IOT up to a year after they graduate.
One thing I reckon will come out will be a rise in the pass score for aptitude tests for aircrew at least, which will affect those applying to OASC in the normal way. I can't guess on how high the bar will rise, but it seems pretty likely.
