JFC can we get a sticky or something that explains what happened. People can't look at the hundreds of threads about this same topic.
Yes Lucy's VA got into some trouble, but in case you didn't notice they recently released OVA 5, and they were still doing anime episodes after she was arrested. Character's voices change all the time it wouldnt be that big of a deal if they had to. Certainly it would never signify the end of a whole series.
FT was "cancelled" because it got to close to the Manga, it is a simple as that. It is already been stated it will be back, it took all of what 5 months for that to happen. Would you rather have 2 years worth of crappy filler episodes like Naruto or just take a break?
If and I mean if they had to cancel the show because Lucy's VA got arrested then there would be a number of unreleased episodes, they don't record them a week before they air. (unless you are South Park)
Just look at the way episode 175 ended, do you really think they would close the anime like that? It is different from Bleach where they made it look like the series could be over.
