If you mean the guild within the story, I doubt it. They'll surely survive.

If you mean the story itself, I don't think so either. There are too many unresolved matters for the manga to end anytime soon.

In my estimation Fairy Tail will continue for at least one more arc, after the Tartaros arc is over and will continue for at least one more year.
