I'm fine with a delay before it's playable but if I'm not getting it for being subscribed in September just because it was delayed, I'm gonna be an unhappy customer.

So Nautolans are free to anyone who is subscribed sometime between September 1 and release date... Does the rest of the expansion follow suit? If my sub expires at the end of September will I get the expansion or will the delay require an extra month of sub to get it? I won't be subbing for October either way. But the answer here will determine if I make any future purchases or subs for future content.
