The Fairy Tail anime ended in March because it was catching up to the manga too quickly (it also ended mid-story arc 9.9) and has been repeated since then. I imagine that what they mean by a "relaunch" is, once the repeats have caught up with where the anime finished, it will start up again with new episodes.
They really need to take their time with it though. The manga has still only just finished the story arc the anime was on when it ended.
