Yes, very interesting. Very speculative too, however close to the situation he is.
I also expect there will be differences, but I fear the changes will all be in an effort to increase
WotC's monopoly rents on its IP to the harm of the larger market (including the players). Anything that harms the cycle of innovation and feedback in game theory and game design means lost opportunities for us to have really awesome games.
Naturally of course
WotC going out of business because anyone can resell the whole PHB (an extreme example) also harms innovation, since they have less incentive to do all that hard design work and playtesting. So a balance must be struck. But my concern is that
WotC will move along the scale further from Linux and closer to the RIAA for apparent short-term benefits to
WotC but to the long-term detriment of the gaming community (including
WotC too).
I hope they hired some good economists and market modelers before coming to any decisions, rather than relying on corporate's "gut instinct."
