At E3, Sony demoed its new wand controller. Actually, Sony demoed two of them. That doesn't mean you'll necessarily have to buy two of them, though.
"The ultimate goal or wish for us is if you have two controllers," says Sony exec Shuhei Yoshida, "like we demoed at E3, we can do something really amazing."
That's the ultimate goal — the short term goal is "making the entry barrier as low as possible". Yoshida continues, "But because of cost-of-goods and, you know, people have to have the PlayStation Eye camera as well, we are approaching the launch by making sure that all games that we create can be played with one controller and the camera."
Sony plans to introduce options if players have more than one controller, and gameplay will be "enhanced" for those who purchase.
But by not making two controllers a requirement out of the gate, Sony could be signaling to third party developers that supporting two controllers isn't a requirement either.
