So, let's see what we've got so far:

• Mount: The current K-mount.  (wise move, Pentax)
• Name: K01   What's this, the guy that thought up the *IST name comes back? 
• Same sensor and LCD screen as the K-5.   Can't go wrong with that.
• Shutter speed to 1/4000 p to 30 seconds.  Meh.
• HD video.  Meh too. We'll soon have that on frying pans and toothbrushes.
• Contrast AF, AF 81 Split screen focus.  Interesting!
• Black & white body color (black keynote), white and black (white tone), black and yellow (based on black and white,
  yellow leather) three different colors.  White & Black?  Oh yeah, the Star Wars Saga continues!
• ​Designed by the same guy that did the Talby Phone.  That should be the cousin of the *IST guy. Horrible stuff.
• ​Looks more like an Optio than anything else. Expected after reading the above.
• Comes with a new lens: DA 40mm F2.8XS + 3 more lenses.   So, 60mm f2.8 equivalent if cropping factor remains at 1.5
• 121mm width, 79mm height, 59mm depth, 560 gr weight.  m43ish weight & dimensions, m'kay.
• ​Pop-up flash.  Obvious, really. Its like saying 'battery compartment' or 'tripod socket' 

​There you have it folks, a mirrorless k-r that will probably be really, really ugly.
