Well, this is only speculation, but since they told us (assessed in europe) that further information would be given once US and other countries have been assessed, i dont really know how long you would have to wait for another assessment in Europe. Know that, from this spree of assessments, November's batch, and future courses next year will already be covered. So, set your priorities having in mind that you might have to wait a long time, and that if you continue training beyond your PPL then etihad would rule you out for a Cadet Program.
Good luck
