This game will no doubt sell well, if nothing else just based on sheer name alone. On top of that, it is extremely likely that this will be a good game. However taking into account the fan base based on sales numbers of Diablo 2, I think that to estimate this came selling more then 10 million copies at this point in time is probably mostly excitement over the announcement. I'd say 10 million is a fairly safe number, but to estimate more than that right now would be a big risk. 14 is pretty chancy considering the dwindling market for PC gaming. We can not expect this game to sell WOW numbers even if it does have the same developers.
