I should've kept on buying those steelbooks, but only got the first 5 of the new ones - S1-4 & Specials, because I only had those on DVD in big digipacks. S5-7 already had on BD in season digistacks, and S8-10 in a Capaldi wide book boxset.
But then again the female Doctor Seasons 11-13 were released in digipacks, which I always pick over steelbooks...
So the whole thing is all over the place, I guess kinda like the series and Doctors themselves.
