This is a new business model for WOTC, one they have been experimenting with, successfully, since the Revised Star Wars game. It's a model White Wolf basically perfected called "revise, reset, resell".
Well, "Star Wars" isn't exactly the top-lne seller fro them that it shoud have been.
I don't have $$$ figures, but it seems that canceling a line after the revised Corebook isn't what I personally would consider sucessful.
And White-Wolf?
Shot themselves in the foot, at least with me.
I have pretty much everything they printed for the orginal "World of Darkness" line (barring "Demon: The fallen", which I hate with a passion.)
So, when they "revamped" the WoD, I said "Enough"; I voted with my dollars, and WW will not get a red dime from me for the newWoD. Does it hurt them finanically? Not at all, I'm sure.
But, if a whole bunch of gamer felt the way I do, maybe it DID hurt them. WHo knows?
Now, they're goign the same way with Exalted. (After teh 2E rulebook, they're reprinting and revising "The Dragon Blooded".)
And after sticking through 3(and a half) editions of D+D, I (and my group) are ready to call it quits. We're NOT upgarding to 4.0. (Hell, my "Shackled City" campaign probably won't be over by the time 4.0 comes out!!)
