It's a little tough to find the most appropriate place to put this comment from Yoshida, so I'll take the easy way out and put it here. Yoshida made this post fairly soon after the announcement first hit and I want to make sure everyone sees it here, too.

The new FFXIV is an extension of the current FFXIV.
We will continue to work hard and update the game, so it would be great if you would continue to provide feedback!

The feedback that the community provides will help build the new FFXIV!
Another thing I wanted to remind everyone, we created a sticky thread to gather all of your questions regarding the announcement, that we will use in the next Letter from the Producer LIVE! So if you want to make sure your question is seen (amongst the sea of new threads being created...) make sure you ask it there!
