Whether or not you like surprises, Amazon(s amzn) seems to. The company is teasing a launch event on June 18 with a video depicting people interacting with a product that's never actually named or shown on-screen.

Is it the new Amazon phone the tech world has been speculating about for years or some new 3D feature or motion-responsive interface in an upcoming Kindle or Kindle Fire release? We'll have to wait to two weeks to find out definitively, though Amazon does give a few hints.

The people in the video appear to be reacting (all positively, of course) to an object or the screen of a device they're holding in their hands, expressing surprise that whatever they're engaged with was responding to the movements of their heads and bodies. "It moved with me," says one of the unnamed interviewees.

Whatever it is, we'll probably be able to get you some additional details about how and why it was created when it launches. Amazon CTO Werner Vogels will be speaking at Gigaom's Structure conference the same day.
