One of the crazier things Razer has on display at this year's edition of CES is Project Valerie, world's first gaming laptop with three 17.3" displays. Each display has a 4K resolution with NVIDIA G-Sync support and the display setup uses an automated deployment system. The three panels use IGZO and offer full Adobe RGB gamut and a 180-degrees viewing angle.
Razer says the system is less than 40mm thick, about same size as average 17" gaming laptop.
With exception of the three panels, the specifications should be largely similar to the Razer Blade Pro, so you can expect options with high-end Intel CPUs and NVIDIA GeForce GTX 1080 graphics.
If the system makes it to final production phase it will probably be crazy expensive too.
