Interest is the core of any business, and it shall come (or not) once K-1's success will be confirmed.
As Ricoh's rep. has aknowledged, Ricoh didn't spend time to push third parties K-mount lens production.
It never was their priority, and it is easily understandable.
But if Sigma for example sees business opportunities in the K mount, because of higher sales in K-1 and/or K-3II/K-S2/..., things will change.
K-1 in itself could push up Pentax DSLR sales, being considered as a real flagship by Pentax customers or newbees, and stop part of the past bleed for the reason there was no K-mount offer in FF.
But of course, time will tell.
Imho, we could see 1 to 3 new Sigma lenses made available in K-mount by the end of this year.
