The images come from HelloMotoHK, and do give a bit of info, if they are to be believed. The front panel alone isn't that much bigger than the Moto X. It looks as though the extra screen size is being gained on the top and bottom, as those bezels are smaller. There basically wasn't any room to shrink the side bezels from the Moto X anyway. Given that the display is expected to be 5.2-inches on the X+1, compared to 4.7-inches on the Moto X, it would seem the screen-to-phone ratio is going to be pretty impressive. It is also clear that the front speakers are going to be quite a bit bigger on the X+1, and are definitely set up to be stereo speakers.
Overall, it is looking good. The rear speaker on the Moto X was surprisingly good, and showed impressive machine work on the wooden panels, but front stereo speakers are something that a lot more phones would do well to adopt. What do you guys think?
