That sounds pretty typical of what we've gotten since SOD. I've opened a case of every Series 4 set except SOI, and it's always exactly the same ...
75% (9/12) of the boxes are "stable", in that you get 1 Ultra, 4 Supers, and 2 Ultimates. 25% (3/12) of the boxes are "unstable" in that you get 5 Supers and 2 Ultimates, but no Ultra Rare.
Variations occur, but this is pretty much it. Blows the 1:24 Ultra Rare ratio out of the water too, but I've been complaining about that for over a year now. The real ratio is much closer to 1:32.
So I would say to expect a stable box with the correct ratios, but don't be overly disappointed if you don't get a single Ultra Rare. It happens to everyone.
