Should warm up the credit card then - hardware announcements haven't been made at WWDC for a long time. All iPhone announcements are in September.
When the iPhone 5 changed the screen size, we heard nothing from Apple besides a very oblique "we have AutoLayout now, use AutoLayout!", which wasn't anywhere close to conclusive about anything.
The push on AutoLayout since iPhone 5 probably also means even less chance Apple will be forced to admit anything during WWDC.
