New AT&T S5 firmware version topic

I just ordered the AT&T S5 from Costco's website. Does anyone know which android version is the current batch shipped to us going to be?

I am asking this because I know that the current root exploit for At&T's S5 only works for 4.4.2 And I am worried if the S5 shipped these days are equipped with 4.4.4 then I'd be in trouble.
