Apple is an, if not the, industry leader in terms of hardware/UI design. I think Apple is smart enough not to make changes just for the sake of change.
Look at all the other mobile companies that have released "iPhone killers" that have failed. They think they can just cram hardware specs down your throat or come up with some new UI scheme that might have a lot of bling, but is not mature enough to last.
Apple's goal is to establish an entire ecosystem around the iPhone, like it did with the iPod. A strong OS foundation, a massive app and media store, a gigantic accessory market and simple integration with other devices. That is what makes the iPhone so popular, not some matte case, front facing camera or OLED screen.
