Don't you know Blizzard? They don't want to make a great game. They want money, our money. And for that they don't need anything else than mega hype. And they have a master class in hype making, we know it.
Go back in mind for all their promises before D3. And what they did? Crap Action House, filled by bots and crap boring game about holding ppm and yawn hours by hours.
What do they do now? Same thing. A lot of promises and more of them in the future. Wind up hype about D4, then take grant for pre-orders etc.
This company does not deserve any trust in them anymore, after what they did with D3.
