Few days ago Green Man Gaming started Witcher 3 promotion (35% off for Witcher 3 pre-order) and Gamespot reported that on their page.
But today they updated article saying this:
GMG is well known digital distributor and it is official store for selling keys.
UPDATE 1 - CDPR response

But today they updated article saying this:
A representative for CD Projekt Red tells GameSpot that Green Man Gaming's Witcher 3 codes are coming from an "unknown source." As such, none of the revenue from Green Man Gaming's current Witcher 3 promotion will go to GOG.com or CD Projekt Red. If you'd like to buy The Witcher 3 directly from CD Projekt Red, head to the game's GOG.com page here.
GMG is well known digital distributor and it is official store for selling keys.
UPDATE 1 - CDPR response
I would kindly ask our fans no to buy via GMG at this time. We had not sold them Keys and dont know the origin of them.

Just a few words of explanation:
We have worked with GMG in the past for w2 and they were a legit partner.
We control all digital and the codes, and because we decided not to sell Keys to GMG it came as a suprise that they are doing a special promo without buying Keys from us. We have reach out to ask for the source of they Keys but up until now there was no response. They might sell nVidia Keys (which are not to be sold but gifted with the nVidia promo), or they just bough Keys from gog just like a regular customer and now they resell them with a loss (we cannot prevent anyone from selling something).
They also list Bandai Namco as the published which is not true for w3 (namco is our box distributor in PAL), so GMG is not a CDPR partner for W3 but they still might sell Keys that will work.
UPDATE 2 - GMG response
"Following a six-month dialogue with [CD Projekt RED] about the launch of The Witcher 3, we were disappointed that despite the offer of significant cash advances, and other opportunities to officially work together, (we even offered to fly to Poland to discuss in detail how we could and wanted to support this launch), CDPR chose not to engage with a number of significant, reputable, and successful retailers, including ourselves, as they instead focused on supporting their own platform GOG. " Sulyok said.
Sulyok explains that GMG chose to essentially go around CD Projekt RED by acquiring digital copies of the game from third parties and retailers that were approved by CD Projekt RED. According to Sulyok, this means that CD Projekt RED is getting the revenue from sales of these games, and that any additional discount is absorbed by GMG. Earlier today, CD Projekt RED told GameSpot it was getting "zero" revenue from these sales.
