I would absolutely love it if we got the device depicted in those dimensional drawings. I think the size of it is absolutely perfect and, being someone who reads a lot on my iPhone, would welcome the increased screen size.
Yet, I feel in my heart that we are just getting the 4S. Maybe those drawings are for a future iPhone or a design that has been scrapped by Apple. Whatever the case, I don't see us getting that phone today (even though I hope I'm wrong).
It still intrigues me that these case manufactures are so confident in the design that they put these cases in mass production. With the economy the way it is, it doesn't make since that a company would mass produce a product on a "hunch". It also intrigues me that companies like AT&T are purchasing and stocking the cases.
All I know is that today's announcement will be surprising, either good or bad.
