Razer has finally updated the QHD+ IGZO panel on their 14-inch Blade with a new UHD (4k) panel as well as swapped out the i7-6700HQ for its 7th generation Kaby Lake counterpart. The Kaby Lake processor should help battery life, but the 4K display is likely to severely punish the Blade's 70WHr battery.
