As we're part of the developer program we are given early access to both Apple's new developer tools and the iOS 8 Beta so that we can get our apps ready for the launch of iOS 8. This is the whole point of Apple giving this early access, and there are already many apps in the store that are iOS 8 ready. We've not provided any date of the launch of iOS 8, but are simply getting ready for it's launch in the near future.
Oh yeah... Extensive bug testing for iOS 8 update? Bump for historical purposes and mostly just the first 2 pages
