WatchKit
An interesting tidbit from the HIG (https://developer.apple.com/library/prerelease/ios/documenta...):Create prerendered animations using a sequence of static images. Store canned animations in your Watch app bundle so that they can be presented quickly to the user. Canned animations also let you deliver high frame rates and smoother animations. Creating animations dynamically from your WatchKit extension and transferring them to Apple Watch adds a delay before playback can begin.This is not a good sign as to the power of the watch, unless I'm drastically misinterpreting things.
