I'd still consider Sega CD and 32X as add ons even if they used different formats. They still needed to be docked to the Genesis. Also, they would be listed in wikipedia under the the 5th generation if they weren't considered add ons. The successor to the Genesis is listed as the Saturn. Just two ways of thinking about it but I am going to stick with how it is listed.
