Amazon has put out word of a June 18 mystery event at which founder Jeff Bezos will launch something new.
Online speculation immediately centred on the potential for the Seattle-based online titan to unveil a Kindle smartphone, perhaps with 3D graphics and motion-sensing capabilities.
Amazon invited people to request invitations at website amazon.com/launchevent and even put out a teaser on the mysterious event in a video posted at YouTube.
The video, titled "Find out what these Amazon customers are talking about", featured people admiring something they were holding out of sight of the camera.
Comments included "it moved with me" and "it's very real life and uncomparable to anything I've ever seen".
