French tech blog, NoWhereElse.fr have published images in what they claim are components for the loud speaker modules for the iPhone 5S and iPhone 6. The images comes from what they claim to be a source connected to an Apple component supplier.
The site believes that Apple will shift from their usual one iPhone per year schedule, and release as many as three new iPhone's in 2013. The iPhone 5S will be the usual, slightly-better-than-the-last iPhone, while the iPhone 6 will be a substantial redesign, but no details have been reported on the differences between the two.
The third iPhone that we could see would be the rumored iPhone Math, or iPhone+ and would sport a bigger screen to compete with the 'phablet' section of the market, competing with the likes of Samsung's extremely successful Galaxy Note range of smartphones.
If the rumored reports are true, we could expect Apple to release one of the models somewhere in Q2 of this year, with the second released toward the end of the year.
