Any ETA on the return of stats?

I apologize if this thread has been done before, I tried searching and nothing similar popped up.

When can we expect the Stats function on custom sets to come back? Mine has gotten past the 200 cards mark and it would be extremely handy to be able to see which color needs more type diversity or mana spread. The old Stats button was really handy for that and I'd take it over not having it at all for months...
