Maybe they realised that ACIV wasn't actually different enough from AC3? It refined what was already there, not reinventing them like Unity, so it makes sense for this to be the "fresh start".

I was also going to make that point about them moving away from Desmond because it's a "fresh start". It only seems logical, so as not to alienate new players.

I should also point out that I believe that HijoDeAguila is right. They were probably friends, & most likely part of the brotherhood. Arno's adoptive father probably told him about the order before his death. I would like for Arno to be born into the order. If this is the case, then it sounds like a similar setup to AC2. I'm not complaining about that, as it sounds different enough.
