he never said that it will return immediately. they haven't even announced a release date yet. We don't even know if they started production.

Since Hiro Mashima was the one who announced it, im sure he'll be the one to give the producers the green light for when it returns.

As for the animation, they do have a certain budget. They can't use the best animation for every single episode.
