I understand that the point of any business venture is to make money, and that even the people that I hang out with online and off aren't indicative of either D&D fans or FR fans as a whole, but it does bum me out and pretty much kills the setting for me. I'm not saying that they are evil or horrible for doing it, but it does seem a bit like gambling on a greater influx of new people while accounting for fewer leaving the setting, and I'm not sure that betting on getting people into the setting that never liked it is the best way to go, but it may work.
It also seems like the assurances that "Drizzt and Elminster are still there" are the concessions to trying to keep older fans, but to be honest, I'm less worried about those two than I am having Cormyr, Waterdeep, the Dalelands, and the like with their "feel" intact. That goes way beyond NPCs that very few people in my campaigns over the last 20 years have run into.
