Don't know why people say it's big, it looks pretty small to me. Assuming that screen on the back is the usual 3 inches, this camera is considerably smaller than the K-5 (same conclusion if the shutter button and mode dial are the same size). From the back angle, it also appears to be significantly thinner.
K-5 inspired looks aside, it seems like a pretty standard superzoom bridge camera to me.
And to those with wild speculation about interchangeable lenses or APS-C sensors, stop.
Just please stop and take one look at the lens.
