Mark, I think there is a very fine, but very important point raised by your initial post in this thread. I don't think this potential setting is something that the fans were necessarily clamoring for, but rather is what WotC hopes that fans will be clamoring for. I don't know how much of a factor market research was in the selection process, but I think that WotC might have "gone with its gut" on this, rather than choosing it as a response to what they know the fans want. If this is so, it may be they realize that trying to catch lightning in a bottle again involves more than hedging one's bets by checking polls and past sales figures.
I'm more or less neutral, by the way, about psionics, so this scoop doesn't really get much of a response from me one way or the other.
And I'm surprised nobody ever registered The Dragon before now...
