So Fairy Tail Zero anime coming in January, prediction on how it is going to effect this anime.

Will it be its own separate thing, and Fairy Tail (2014) have something else differently?

I doubt that, what I think is going to happen, that officially Fairy Tail (2014) will end in December, and Fairy Tail Zero will take its time slot and be a 12 or 13 episode anime (which would mean adapt 1 chapter per episode so lot of in canon filler), and in April either they adapt another spin off like Ice Trail, or they adapt the Avatar arc and that will be the start of the third Fairy Tail anime which would be Fairy Tail (2016).
