I don't think the SW name ought to mean anything to anyone, except fans.
It isn't really a series or a 'programme', they're going to call the next new coaster "SW" no matter what happens. It never had any meaning after Nemesis was finished, it's always been just a 'cool' promotional tagline to get people talking before the real name is announced. It certainly isn't connected to John Wardley, who shouldnt really get sole credit for what he did on the previous coasters anyway.
Nothing wrong with a bit of tradition, apart from when it's made out to be some kind of certification of world class innovation. From who? The Secret Weapon Board of Excellence, obvs!
