Has the idea of a 5th grand slam ever been suggested? There are hundreds of smaller pro tournaments around the world but all the excitement is focused on the slams and to a lesser extent the atp/wta finals. TV viewing/revenue ets for any of the slams must dwarf the other tournaments. My suggestion would be a 5th slam in possibly Japan, China or Korea. This obviously would require revamping the tennis calendar. There is a decent gap between the AO and the FO - maybe it could be then. Some questions that might need to be addressed: What surface could it be played on? Would it be able generate the same level of interest? What would be the pros/cons? It's an interesting though/discussion point at least and I'll be interested in what people have to say.
