TW.Apple.pro has posted drawings of what's suggested to be the next-generation iPhone. There's little more here than sketches of iPhone parts, but they do seem to line up with images from a YouTube video of suspected "iPhone 5" parts. That video was recently pulled from YouTube at Apple's request, suggesting validity.
One point of note is that the break in the external band that forms the antenna has been moved. We can only assume that means a new design will be in place on the next iPhone. We couldn't glean any other major revisions from these sketches, but you're welcome to take a crack at it.
