Then again, this might be a good thing, as it would give more time for the localization team and translators, thus reducing the risks of mistakes.
For CS2, some of the english voice actors weren't available and therefore had to be replaced temporarily.
And as for Extend...in CTR, some lines were actually left undubbed and there were other times when the text and voices didn't fit (IE, Bang's line about Jin's ice cars).
And on the topic of Xrd, I'm pretty sure ASW want it to be a big popular title, so its NA release may actually be not too long after the JPN release...though it might take much longer if they're getting it dubbed.
