You've probably heard that Wizards of the Coast has announced they will be reprinting the core 2nd edition books, plus some adventure modules. I will not be buying them, but I think having any of the (current) four editions available is a net positive. The one thing I think they did wrong is release them as collector's additions instead of books meant for gaming.
This decision has me questioning their end game. I don't think Wizards actually want to maintain active support of all of these editions. That these reprints are being released while 5e is being assembled makes me wonder if Wizards is looking to gauge which previous edition they should emulate most. I know this is a cynical view, but I sincerely doubt they released these reprints because fans want them. If nothing else, I'm willing to bet they were reaction to the OSR and Pathfinder. After 5e drops, whenever that is, what's the likelihood that Wizards will release Collector's reprints of 4e?
