It appears that ASUS G752VS is the first notebook reported to feature new mobile Pascal graphics solution.
ASUS ROG G752VS
This model will be available in few variants, but all of them feature the same graphics card — GeForce GTX 1070, and the same CPU — Intel i7 6700HQ. The cheapest variant doesn’t have have SSD. It will cost you 2000 EUR, but of course prices for other regions will be different (and so can the specs).
You have an option to choose ULTRA HD (3840×2160) model for 500 EUR more, but is it worth it? I think it depends on GTX 1070 mobile specs, and how they changed from desktop variant, because even GP104 can have trouble delivering very high framerate at 4K.
More importantly, this post from LaptopMedia confirms that NVIDIA is not using M postfix for their mobile Pascal series. Mobile GTX 1070 will also feature 8GB GDDR5 memory (and so does mobile GTX 1080).
Anyway, here are the full specs, you can see all available variants by following the link below.
