Only Ricoh knows. And maybe they don't either.
Only a few reasons to drop the price:
- keep your product where you want it on the value curve in relation to your competitors
- move out inventory either to get ready for a new product or to keep inventory movement on schedule
At this point the K-1 is kinda king of the hill on the value curve. And currently demand seems to remain high. So not much incentive for price dropping. In the past Ricoh has started with very high pricing (sometimes way too high like the k-01) and then dropped the price as they saw what sales were. For the k-1 they seem to have gone in a different direction by releasing it at an extremely attractive price and hinting that the price was going to remain stable. This makes sense for a 'professional' product where knowing replacement costs might be important whereas a consumer camera is going to devalue fairly soon as new products come out.
Bottom line: don't hold your breath for a price drop.
