I still think the real reason for the delay was an inability to get shelf space, which isn't Atlus's fault- they got bumped by bigger publishers. SNK probably delayed outright, because it doesn't hurt them, and they get more time to polish the netcode up. Inability to get shelf space happens plenty to smaller publishers- and is a reason why many games have gone DD.
I think it if was truly a quality issue, Atlus wouldn't have been so set on the new date, and I don't think we're getting a second delay now- the game looks ready.
