Reforging: Spirit a Primary or Secondary Stat

Pardon me if this question has been asked and/or answered already some where else.

In a recent interview Ghostcrawler said:

Q u o t e:
It then asks you to pick a stat to reduce, and then pick a stat to add. You can’t use primary stats like agility, strength and intellect, but you can use all of the secondary stats like hit, crit, haste, parry, dodge, things like that.

Is Spirit concidered a Primary Stat or a Secondary stat?

Traditionaly it is placed among the primary or base stats like Int, Stam, Strength, and Agility, but in Cata, it seems like it will behave more like a secondary or "rating" stat in my role as a balance druid.

It is likely that I will get a good portion if not most of my Hit chance from Spirit rather then Hit rating, but if can't reforge my Spirit, I lose a big tool to help me balance my Hit chance.
