The Pentax Q System*yawn*. It's going to be the most expensive tiny-sensor camera since the days of the Canon Pro90 IS. It's pretty much like the new version of the Pentax Auto 110 system.
And this time, it may not actually sell that poorly because it's sexy, retro, better than a cameraphone, and everybody's used to small sensor cameras. But I'm pretty sure that I'm not the intended audience.
