In addition to the upgraded Blade 15 Advanced, Razer is also showing two interesting prototypes at CES. The first one sports a 240 Hz full HD display, while the other one comes with a 4K OLED touchscreen. Sadly, these might not make it to the masses anytime soon, since both are only being evaluated at this stage.
