Given this should they be wedded to the K-mount? There are advantages in looking to overhaul the entire system.
Releasing new "HD" lens line in K-mount would be their best potential path, given the potential pre-made market of existing K-mount users, some whom would be happy with a K-5/7/r/x or next gen APS-C etc and a HD lens, while many others like myself would opt to step up to FF to take full advantage of the new lenses and get the maximum potential from their current & discontinued lens lineups. If the new lenses they would make for a FF option were truly superior to their previous lenses, people want that level of IQ would purchase them PERIOD. IMO it would be like having a Takumar Bayonet 135 f2.8 and upgrading to an FA-135 f2.8, it's not about making a whole new lens, it's about better glass refinement/QC and optical glass coatings. Another bonus on revamping their lineup is the ability to ditch SDM from their lineup and goto DC or a revamp/amalgamation of both.
I do not see the "benefit" of ditching the K-mount. Changing mounts would only force people to say "Well that Nikon D800 (or D3x/successor) or Canon D1X etc looks pretty good and has a much broader lens lineup with an established mount." I know people looking to move to FF are already forced with a mount change and loosing their lenses already. Making people choose a new mount for FF would only add to loosing more perspective FF body purchasers.
