According to some info published a few weeks ago by the Pentaxeros.com (spanish Pentax forum) administrator, there will be TWO new DSLRs this year to be released at Photokina. One between K-X and K-7 and another one ABOVE K-7. And judging by the way he talked about this last camera, it could be a full frame camera.
Quote: Personally I think it will be a model BELOW the K-x.
Price wise the K-x is not an entry level camera and they need something that will tempt P&S shooters.
K-x is an entry camera. Currently, in my store, at €499, it's almost as cheap as the Nikon D3000 (€439) or Canon EOS1000 (€459) and with way better specs.
