My guesses (since the specs haven't been announced) on how it'll be souped up over the Style/Pure Edition....
- Snapdragon 820 (versus the 808 in Style/PE)
- Wireless Charging (not present in Style/PE)
- new screen (as mentioned by the OP and the tech articles)
- USB-C charging port (yes... this would be awesome)
- BIG BATTERY (possibly 3800mah+ like the 1st Turbo versus the 3000mah in the Style/PE)
Other than the possibility of USB-C, most everything above is similar to how the Turbo differentiated itself from the Moto X 2014. I think if they get most of these enhancements into the phone, it will more than justify the higher price tag. Bloat doesn't bother me, it can be disabled. It should have the same Moto software on top of v5.1 or v6 that the Style/PE will have.
