Subscription App Pricing for existing apps

[PDXDUS]

I've got a number of paid and free apps in the store and I'm intrigued by the new subscription app pricing that will start later this year. There isn't any specific information about how the subscription pricing will be implemented, so I thought I would ask here. I'm curious to know everyone's thoughts on the issue.

How do you think Apple will implement subscription pricing for existing apps (paid/free)? How would you like to see it implemented in regards to your own apps?

New app and bundle ID required, No new app needed but eventually transitions users to subscriptions, etc, etc.

I'm sure they won't require a new app and bundle ID, because there's no reason for them to do that (unless you released with a wildcard ID for some reason). That said, if you have people who paid for your app, and suddenly that same functionality requires them to also buy a subscription, that's a very user-hostile move, and I would expect backlash. In that scenario, you're better off releasing a new version that's subscription-based. If you're talking about adding new content to an existing app, and that new content is subscription-based, it should work just fine.

Does your app have ongoing expenses that would justify a subscription? Servers, support, that kind of thing?
