I suspect the timing didn't help.
I agree with that, thinking something is going to be announced does not mean it's a failure if they don't, it was never in the plansand only your mind made up this miracle place
It's like expecting someone to give you candy, when they haven't even bought candy or talked about candy at all.
I don't think its a case of "Oh they didn't announce anything new, bunch of cunts" I think it was more a case of "It's the 20th and 10th Anniversary and they've done almost nothing apart from a 1 hour documentary that would make you think so" even something simple like going "oh we've fixed wacraft 1,2 and 3 to work on the battlenet launcher/latest os's would have been something.
