What's next for Siri?

With the combination of the touchless control and Google Now on the Moto X, this is a real competition with Siri, but with Siri, you still have to press and hold a button.

Like Scotty said, "How quaint." :)

Will Apple implement some sort of touchless control too? Considering how Apple is trying to go into car's infotainment system with the "Eyes Free" program (but that one still requires a button push, I think), do you think Apple is already on it?
