Biggest card surely was when AC13 delayed to Nov was to release ASAP at that time. Dev window still too short for AC to successfully copy, he has said that console versions have locked. To me a no-brainer, would have given him exactly what he mentioned - people wondering about pre-ordering AC13 find another awesome cricket game already out. HUGE opportunity missed there, I feel.
That being said, as it's called 14 it'll be late Oct/early Nov.
Hardcore will probably buy both, so BA need to maximise the rest. If I were BA I would want DBC14 out and established as THE cricket title well before christmas, because otherwise Mums who know nothing will see Ashes and buy that for their kids. But if DBC has set the bar already, the guy in the store does exactly what Ross wanted, and says "there's this other game..."
Possibility is BA don't think AC will make it at all, even in Nov and want to drop the bomb then.
