They need to cover the refresh of common lenses first. Pentax offical have mentionned 3 new lenses in "near future". The 28 makes the most sense given the crop ratio, the 35 wasn't anymore wide enough for the lower end of focal length. The 2 other lenses would be an 85 equivalent and a standard weather-sealed zoom, I wouldn't be surprised.
After that you can go on with the specialty equipments (shutter plane lenses, tilt-shift, ultra-fast, long tele etc...) Given the excellent 6x7 and 645 film legacy glass there is no emergency.
