For those users who have the interchangeable-lens DSLRs, the purchasing cycle, to start with, was not very short, so they would use the same camera for several years. So this would also cover your next question as well. <laughter> In terms of the camera model change cycle, I think that would differ based on the characteristics of each camera. So in terms of our high-end cameras, we will do our model change when we are able to embed the functionality and performance that we are aiming for. For entry level models, of course we will do the model change when we come out with new features or new performance. But at the same time, for the entry level models there is a lot of competition, and so we also have to work on cost reductions. Once we are able to do these cost reductions, that would be another opportunity for model change.
