One of their previous "desktop replacements" was about the same size, and weighed about 12kg, so this is an improvement. Think twice about using the word "portable" in a sentence when this thing is discussed, that 8kg is probably without the power adapter which might break another record on its own.
I was never a fan of convoluted gaming laptops like these, way too heavy and immobile (because battery life is non-existant) to be used as a laptop, so you're basically lugging around an all-in-one desktop with a foldable keyboard, which doesn't fit any laptop bag on sale (for the size and weight), still needs a mouse, desk, closeby power outlet and when something breaks, it's going to be immensely expensive to repair.
