A mysterious new Philips Hue lamp just leaked, but is it actually coming soon?

Philips seems to have accidentally leaked an image of an unreleased Hue lamp on its own social media pages, before the post was quickly taken down. Does it suggest something is coming soon, or was it simply a mistake?

The image in question showed a floor lamp with a ring-shaped light perched at the top of its tall stand. The light seemingly shines out in two different colors: a subtle colored ring on one side, with a wide, dispersed colored light on the other. At the bottom is a foot-operated switch, presumably for turning the lamp on and off.
