Games industry is a business. Since FF sells absolutely enormous amount of copies, SqEn will keep making it. If the sales ever start to lag, we can start talking about the series ending. Thus far, each episode has sold huge numbers (and spawned off a mountain of merchandise for even more profit), so of course new games will be made.
SqEn is a business, and their job is to make profit. FF series fits the bill. Case closed, at least until the sales figures of the next FF come in.
