I agree that the pace of the margin expansion is not sustainable, after all, the cost cutting is all behind it and probably was the initial catalyst to start a margin expansion period.  However, if there was an inflexion point where digital downloads increases markedly, say from 20 to 50% in a short period of time  (a terminal rate of decline for GME, i.e. an inverse relation), then the margin growth could still be significant enough to still be considered bullish for the EA. 

I am simply wondering if this is another trend that could grow longer legs, after all, trends tend to behave this way.  Just a thought.
