So for high-end thin & light gaming laptops, such as Gigabyte AERO 15, Alienware m15 and Razer Blade, which PCIe version will they support by 2021? 4.0 or 5.0? Is 5.0 even made for laptops? And if so, will it use 4 lanes or 16 lanes?

It's hard to saturate PCIe x16 so gamers and home users can wait before getting the new standard. Dual Titan V were bottlenecked by PCIe x8.

Consumer PCs will finally benefit from PCIe 4.0 devices this year thanks to AMD's support via the Ryzen 3000 CPUs, but the high-end sector will also be getting a taste of the PCIe 5.0 some later in 2019, and the two standards are expected to coexist for a few years. PCIe 5.0 will push the theoretical bandwidth to 128 GB/s on x16 duplex lanes running at 32 GHz.
