Some musings:
Its funny, Pandaren were cool when everyone loved Blizz and they were included in WCIII. But now that hating on Blizz is cool, Pandas are lame.
Somehow I feel D3 did more to hurt sales of MoP than WoW itself.
Any analysis should include digital sales, even if it is an estimation based on recent purchasing data.
Looking at the Acti-Blizz earnings report, its hard to imagine that they get more than 50% of their sales digitally. Online channels account for 32% of revenue 20% of which is subscription fees leaving 12% maximum in digital sales if we pretend that no revenue is made from DLC type content. If we factor in the 26% platform percentage for PC sales, which all Blizz games are, then 46% is about the maximum that could be attributed to digital delivery.
Granted its possible, being an x-pac for an online game, that the percentages are higher for MoP.
Its also possible that, being early and not having slept much that I completely borked some simple math or am overlooking something in the earnings report.
