For sure. Design-wise (including the bezels), the iPhone 7 is so far looking incredibly uninspiring. Especially for Apple caliber. Maybe they're saving their best for 2017, but until then I share the same feelings as you if the leaked designs all prove to be true.
They took one tiny step in the right direction by trying to eliminate the antennae lines, but then turned it upwards to frame the device in this weird double U-shape pattern. And worse, they continue to make the band color contrast the actual device color. And, as you've mentioned, they've done little to nothing to improve the bezels and overall footprint of the device.
Given that there is so much room for improvement on the iPhone 6S design, the leaks are disappointing and lackluster. During what we traditionally know as a redesign year, too.
Heck, some parts of it are downright ugly -- the aforementioned antennae lines, and the double camera housing with that weird crater-like hump. Not a fan at all.
My excitement for the new home button is purely to get everybody to move away from physical home buttons on flagship devices. It's about time.
I'm also confused about the whole antenna thing. I never thought they were a big deal, they simply needed to color match them and it seems they went to a heck of a lot of trouble for nothing. Especially seeing how they are still two toned, well if we believe the rumors.
I'm hoping against hope that Apple surprises us. They are usually the masters at secrecy and I honestly think not a single one of these leaked photos are authentic. The market for iPhone clones is humungous, and there are already tons of iPhone 7 clones even though no one knows what it will look like. IMO we are basing our predictions on what some Chinese clone manufacturer decided the iPhone 7 will look like based on rumors. I would think that with the success of the S7/S7 edge 6 months ago Apple would have been able to turn on a dime and change some things around. But then again Apple pretty much banks on consumers paying top prices for their products without considering the technology.
