Any now what is this?

It's a 36-slot bag.

So it's a 36 slot on the store tooltip (which is sometimes showing incorrect stats). On the bug tracker, someone reported that it was only 30 slot in the game, a Dev said "yeah, that's it's size in Vanilla". Then the dev comment got deleted and the bug report was marked "Pending" or "Fixed" (pending is usually what it's marked until the next monthly changelog is posted, even if the fix is pushed to the server already).

So is it 36 slots, or only 30? And if it's 30, will it automatically increase until it's 36 slots in Wrath phases, or will we be stuck with a 30 slot cause we bought it during Vanilla?
