Ben Thompson:

But I can see three significant contextual differences between 2013 and 2007, and I think it’s those differences that likely provide the best hint as to what to expect in upcoming versions of iOS.

So what has changed since 2007?

I’d also add that the hardware is significantly different — in particular, we now have a (comparatively) huge amount of RAM on these devices, a major difference from the original iPhone’s hardware that influenced a lot about iOS’ design and architecture.
