Update 4/10/13: It has now been revealed that comiXology banned the issue believing Apple wouldn’t approve it. Stranger and stranger.
Apple has refused to carry Saga #12 via any of its app-based platforms because of two small gay sex scenes, writer Brian K. Vaughan has written in a press release. The issue goes on sale tomorrow and will not be available through anything that goes through the App store. However, as Vaughan explains, the issue will still be available through Image and Android apps.
