In fact they are rumored to be announced on January 24th, 2008. There aren’t any pictures of either camera yet, but below is a picture of the K10D, the camera they would presumably be replacing.
The rumors claim some pretty hardcore specs, even for a DSLR. Those include a 14MP CMOS sensor, a 14-bit RAW A/D processor, 3” LCD, better In-Body shake reduction, PC Syncing, and that’s just for the K20D. the K200D would be replacing the K100D.
