As to the manga, I think it depends on how you interpret stuff. Recently, chapters have been titled "Prelude to the Final Battle" and stuff like that, and we have the idea that Zeref will soon be done in. The idea of Zeref has been an organizing principle of Fairy Tail for some time, so we don't see much of a structure to the series with him and Acnologia gone. On the flip side, Mashima did say that the Grand Magic Games were the half way point, and he just launched a magazine and stuff. There a few ways past this seeming contradiction. First, I may remind you that Zeref wasn't even mentioned until the Tower of Heaven arc, it was just a series of fun wizard adventures without much "glue" holding them together. It is possible that Mashima might do something similar, or make Fairy Tail about the torch being passed to the next generation - after some very "shipper friendly" arcs leading up to children being born. Alternatively, the Fairy Tale franchise might have a while to go, but as another commenter suggested, it will be mostly spin off series, while the main series wraps up fairly soon. Either way, I think the questions "how much longer for the Fairy Tail manga" and "how much longer for the Fairy Tail anime" are two slightly different questions. The anime will either run until the entire main manga series is covered, until only the end of the Tartorus Gate arc, or the anime might start covering spin off series. Whatever happens, the anime will not continue forever on just filler material, so there is a limited amount of anime episodes that can be made after Mashima stops writing new Fairy Tale manga.
