Visiting the Ricoh booth today here in Vegas, I was informed by one of the reps there that Ricoh will be offering an upgrade option for the K1, whereas you can send in your K1 body and they will upgrade the internal components to the the K1 MkII components for a mere fee of around $500. Now..... I cannot vouch for the validity of this info, however this is the "news and rumors" section. This is what I was told by the rep, I wouldn't make this up.
Basically you can end up having a K1 MkII in a K1 body.
