Yoshida posted on the Japanese boards to say that everything'll be all right.
Here's my quick translation (copied and pasted directly from my article, so please forgive the article-like tone)
Final Fantasy XIV: A Realm Reborn Producer and Director Naoki Yoshida immediately took to the official Japanese Lodestone forums reassuring the fans, and clarifying that the change in leadership and the restructuring won’t have any effect on the development of the game:
He also added that the reason why he didn’t communicate much recently wasn’t due to the news released today, but simply because he has been very busy with the game’s beta testing (the first phase has just ended and the second phase will begin within the first ten days of April). He continued with his usual positive attitude:"Please be assured that our development policy, development attitude and development structure won’t be affected at all."
He finally followed up with a further post stating that concern from the fans is understandable and thanking them for it."Our policies haven’t changed at all, and we’re pushing forward to the launch of the new game backed by the support of the whole company.
Actually our sense of responsibility towards the rebirth of Final Fantasy XIV is strengthened. As producer and Director I’m determined and prepared for it and I’m working hard to deliver the best game I can.
Please don’t worry."
Of course if anyone that understands Japanese better than me sees any mistake in the translation feel free to correct me, but it should be all right.
