Developers beyond Sony Pictures Television won't have access to the skill-subscription tools just yet, but Amazon says it'll let you know when that's ready. Like TechCrunch notes, this is interesting for a few reasons; app subscriptions themselves, and how they'll potentially shape the future of the Alexa business model chief among them. Tying the subscription to a Prime membership is a bit odd when you consider that an Echo device is kind of pointless without a Prime subscription as-is, but the company says that not all premium skill experiences will necessarily be free as a part of Prime.
Amazon is still working on a revenue split for developers, too, and told Engadget that it hasn't finalized its revenue sharing model for that. Typically companies take a 30 percent cut for app sales. If Amazon wants to keep these types of premium skills rolling though, it'll have to make it worth the extra work for developers.
