does diablo 3 allow player to micro pets like in titan's quest? like each pet is bind to a key, when you press that key and press anywhere the pet will run to that location. i just thought that this could add much ore depth to sacrificial witch doctor builds- so anyone participated in blizzcon plz confirm this?

Sort of. Direct control of their actions, no, but there's a lot of thought and strategy that can go in to pet control far beyond just summoning new ones when the old ones die.
