The next version of iOS shown off at WWDC should be iOS 8.5 or something. Calling it iOS 9 gives the impression it's a major release with lots of new features. iOS doesn't need a lot of new features right now. It needs bug fixing and polishing of the new stuff added over the last two years. One good thing about Watch is it will force Apple to fix issues with Bluetooth and WiF because Watch will be a terrible product if Bluetooth and WiFi aren't working properly.
