Diagonal StoryBoard scene change effects

The current storyboard scene change effects are great and plenty. I was playing around with IOS 7 running on my iPad and noticed how the scene change animation is implemented where depending on where the screen is tapped the next screen or app etc sort of slides in from that area. This includes the corners in which case the transition is diagonal. Current storyboard effects do not include diagonal slide in / out etc. Will apps work without this in IOS 7? Certainly. Will they feel like IOS 7 apps? Not if we are going for the full on effect. Something else to think about for CL as they ready the SDK for IOS 7.
