At some point Rosewill decided to discontinue the RK-9000 without an official announcement. Beyond a sudden and sustained drop in availability, there was no evidence that the keyboard was no longer produced. A few silent months went by until Rosewill officially announced a second generation of RK-9000 mechanical keyboards. It was then clear why the RK-9000 was discontinued: it was being replaced and updated.
We were approached by the company to conduct a review of their recently released mechanical keyboards. Included was not just the Cherry MX Blue switched RK-9000, but also its three newly introduced siblings: the MX Brown switched RK-9000BR, the MX Black switched RK-9000BL, and the MX Red switched RK-9000RE. A little under three months ago we have received the review units and have been in the process of testing them ever since.
