Back at the start of this month sources began claiming that Nvidia may skip the GTX1080M this generation and bring a modified/lower TDP version of the desktop GTX 1080 to laptops right off the bat. Nvidia already proved it could put desktop graphics in a laptop with the GTX 980 but it looks like that earlier information may not have been entirely accurate as conflicting information has come to light, claiming that we will actually see a GTX 1080M.
IVY Gaming Laptops briefly had a listing up (link removed, see image below) for an upcoming system featuring the GTX 1080M, which according to information obtained by cnBeta, will feature 8GB of GDDR5, rather than GDDR5X.
