I wonder about the line "Concepts for 4th Edition gameplay were tested in the new Star Wars RPG, and the Book of 9 Swords."
Specifically the patch about the Book of 9 Swords. I owned that for a while, and it was pretty ambitious. Key to that ambition was doing a lot to offer melee specialists more combat options in the form of semi-spell effects, reactive abilities, and generally stuff more complex then "I swing, I hit!, I do damage, I repeat." Not tricks, not like SC, more limited by feats/classes/lists/themes.
Nine Swords was, incidentally, not approved material for any Living campaign I knew of (or at least played). Probably due to a cocktail of balance issues (You hit me, I reactively blast you for 4d6 Fire! Whee!) and distaste (as expressed by the local Greyhawk Triad members I'd chatted with at the time) conjured by....creativity! Who knows.
And though I can't find the entry I'm sure I read somewhere the first updated D20 setting will be The Forgotten Realms. I'll admit, that's kind of interesting...I'm hoping FR got chosen to boot Greyhawk as the official setting. Cuz, y'know, Greyhawk sucks thundering buffalo toe. Could be wise, could be brutal.
Since about 1996 the list of local Forgotten Realms fans has diminished under waves of Harry Potter, literary criticism for Salvatore and Greenwood, and the pressure created by those hideously expensive FR hardcovers themselves. That's in addition to the long-gone Living City -the former Living bastion of the Forgotten Realms.
Or in plainer terms, if the change comes will anyone give a crap? Living SoylentGreyhawk is rather popular in the circles I know, though not for the setting so much as the PC's wedded to it. That's just life in the Duchy of Urnst though; chatter at Origins year after year suggests to me a higher degree of satisfaction elsewhere.
Irregardless, I'll probably buy and play. Not for any real love, WTB Classic Fantasy plz, but because it's what will probably be going on most weekends. And THAT is the great decider because even when the mod sucks the company's grand and the pizza's at least decent.
