Well said, 1Mac, excellent points, too.
Personally I think the idea of using the MMO/WoW model of funding development is an awesome idea.
It enhances the tabletop play with extra utilities and tools, but doesn't replaced one of the better aspects of tabletop RPGs, that can be lost to a degree in MMOs, which is socialization.
So now, WotC can fund books via a steady incoming, thusly answering to the Hasbro stockholders, but also have steady funds to poor right into development and keep those steady dollars.
I mean, seriously, if WotC can show the Hasbro BoD and Stockholders that they can sell the equivalent of hundreds of thousands of actions figures ever month, month after month, without the materials or shipping, then I couldn't see them disrupting the company in any way, shape, or form.
It's just an awesome idea that I hope they follow through on, because if they do it'll be an interesting time to be a dice/tabletop gamer.
It's not an MMO, it's a digital tabletop, pure and simple. An extension of our books, our tables, our dice, and our friends.
One of my hopeful thoughts is about the digital edition of the book(s) I just purchased, be it PDF (my dearest hope) or a similar facsimile, it'll cut down on the wear and tear of my back.
