Does anyone know why Fairy Tail stopped at episode 175 and when will it resume?

I heard that Fairy Tail will be continuing:

1. sometime in November,2013.

2. au maybe in March,2014.

Also I heard from different sources that Fairy Tail stopped because:

1. the anime was catching up to the manga so they had to take a break from the anime

2. the voice actress for Lucy is in some sort of scandal au something like that

3. some people think that maybe the ratings drop so the onyesha was cut and the manga continued like what happened to Bleach (which I find very hard to believe)

If wewe guys have any other reasons au maoni to why it stopped au will be continuing please state so thanks
