It's not really the problem of whether we get an iPhone event in 30 days, but the damage to the culture that Apple has built for more than a decade - the very culture that forced the entire market to follow suite and had trained consumers to be accustomed to this new "norm".
From a marketing standpoint, to witness how the very market leader that changed the entire industry to have destroyed the trained behavior of customers? It's just painful. Not to mention that this would take years to rebuild, and most likely not repairable at all.
At least this is how I view the event.
There really is no damage at all, not beyond a handful of tech forum residents. I would wager you can survey >98% of iPhone owners and they wouldn't even know or care when a new iPhone is usually launched, just when they can get a new one through their network carrier. It's not like the next creeping iteration is going to be years away.
