while 5 color crack may be a cash cow still, they still need to have a reason to keep paying people to work on DnD. so if they keep alienating customers they will eventually sell off the copyrights to some one else or just let it die.
and i know they keep getting younger and younger with the magic crowd but they do have larger than normal drop offs in my area every year. that may just be my local gaming area and not a trend in others
