Sonny Dickson iPhone 6 Pictures (4.7in and 5.5in)

So for anyone who hasn't seen these, Sonny Dickson (usually accurate unless I'm mistaken) has posted apparent pics of the 4.7in and 5.5in iPhones.

While I think Apple is definitely doing the right thing here (in terms of screen size), I kind of think the design (rear) leaves a lot to be desired. Doesn't look anything like as nice as the 5S, more like an htc One mini. Plus the side bezels especially on the 4.7in are surprisingly hefty. Saying that I think these leaks would look markedly better in a different colour than gold.

So what do people think? Any idea how big these will be in terms of dimensions? The 5.5in looks positively gargantuan!
