Relax. Its better to ship late than ship garbage.
Well I got some bad news. iOS 8 was supposed to launch today for the consumer. Having been on the Gold Master for Developers for the past week I've noticed some issues with mSafari (particularly memory issues) but nothing that would make it a non-ship.
Yesterday I heard that handoff was not ready for prime time. I can confirm that today. HealthKit also has an issue, and because of that, iOS 8 will not be ready as an update. If anyone has updated, please let me know.
As of this post, the dev portal still indicates we are at GM. Ill update if anything changes.
