It has nothing to do with ratings, as the series still draws high numbers for the WB network. But it could still be canceled by its new network, CW, a merger of the WB and UPN networks. Apparently, the new network is aiming at a different audience than Reba usually draws and may not be interested in keeping the show. The season's final episode of Reba was originally shot as a cliffhanger, but has now been re-edited in case it is the sitcom's swan song.
