Any delays were platform/console based not any fault of Big Ants. The PC version was patched almost daily, usually weekly and play-tested by this community for months, each one being rolled out as improvements were made. Any delays are again, no fault of Big Ants and a symptom of them trying to get the absolute best version of the game out for us all.
to be fair, that's not quite right. there was a flurry of pc updates, a very long break with nothing, and then the final flurry. this is not a criticism, by the way - they more than met their obligations/promises to patch and the amount of improvements given for free was sensational.
i think AJ's point - which I agree with in part - was that there was a lot of delays in the last one: from summer 2013 (hinted at but not confirmed if I recall, though Ross did later confirm that was the initial intention), to definitely 2013, to spring 2014. Now the Ashes feganigans obviously contributed a whole heap-load to that, but equally if we assume
some work was done on the game between summer 2013 and spring 2014, and yet the game was still released with pretty glaring issues in 2014 requiring almost immediate patching (and kudos to them for fixing the superman in the covers issues so quickly cuz they were killing the game!) then the game may have been unreleasable summer 2013 even without the AC13 debacle. (I am not saying it was, but that it might be - only BA now the state of the code at that time and waht work was done between then and release, and Ross was adamant the game was finished and releasable certainly in autumn/winter 2013 which we've no cause to doubt.)
that being so, it's not beyond the realm of possibility that just the nature of the SDLC might push the date beyond 2016, and better to consider that possibility now than throw a shit fit later, hence his "prediction" of 2017.
I would be very surprised however if they don't make the Q4 prediction and i'd be surprised if it's later (or much earlier) than early Dec to hit the Christmas peak.
The other thing I recall from the last one, however is this: it'll release when it'll release, and anybody can find some "logic" or compelling reason why date x, y or z is the best date, and it don't mean a damn thing.
