I don't doubt they will cost more than the Pixel line, but I'm somewhat skeptical that the hardware will be higher quality. Perhaps my idea of what Motorola is capable of is outdated.
Realistically, most smartphones are made by the same ODMs. Since they don't make their own screens, shells, CPUs or modems, the only thing being set apart is the software.
Pixel itself is very mediocre hardware, it's not hard to surpass. The battery is my main problem with it, my current pixel can't barely survive half a day of usage.
Google’s Tensor chipset is weak by modern standards, and Motorola is taking the strongest off the shelf processors from the best mobile chip designer (Qualcomm).
