I don't really see the need for a 2K screen, but then again I'm blind, a 720p screen looks perfect to my eyes. I agree that MS could use some lineup simplification. 5/7/9 and phablet series would be great but I doubt this will happen. They like having price segmentation at all points, although let's not forget there's currently a $200 difference between the 635 and the 735. Maybe they'll kick the 6xx back to the $200 range and actually make a successor to the 620, which was great, while the 635 is quite lacking on screen, camera and memory fronts (but for $99 you can't complain... yet I'd rather pay more and get a better device, just not the unjustifiable $300 for the 735).
