The U.S. iTunes store now has a few Disney Afternoon cartoons for sale. It is probably just to place it under some network for the Disney section of iTunes, but they are listed with Disney XD branding. They include the complete runs of Talespin and Chip 'n Dale Rescue Rangers. They are also offering Ducktales, but that is missing an episode from the comments listed. I hope Darkwing Duck is next in line to get a full release.
