I have to agree, and it's not just the official forums or neogaf (or other forums), but the opinions of people I have played with. Things do seem to be the worst they've ever been when it comes to overall community attitude towards the game/blizzard. Assuming the next expansion isn't revealed until Blizzcon, I imagine it's going to be a long, rough few months for some Blizz folks. And even then, they kind of need to knock it out of the park if they want people to be feeling that WoW hype again.
The WoD hype was probably the most people were excited about WoW in a long time, and since it many ways didn't deliver, I am not sure what they could do for the next one that people will be really pumped about.
