Honestly, the way this is turning out is looking to be bad PR for CDPR. To someone reading the annotations, GMG is biting the bullet and losing money on selling the game for $39, CDPR refused to work with GMG, GMG is receiving their copies from an authorized retailer who's currently unknown.
As someone looking into the box from outside, GMG is the company that's doing things 'Right'(Whatever that means), and CDPR is scummy. Unless something is being omitted..
Cui Bono?
GMG would never simply start selling keys out of the goodness of their hearts. There's no way they're "biting the bullet," as you put it. They're profiting from it.
But more on that in a minute. Let's talk about GMG.
This is the company that recently began packing in 'free' extra steam codes (stuff that costs a couple bucks at most) with certain preorders so that, should you decide to cancel a ($60) preorder, they can point to that free code they gave you and choose not to refund you.
This is the company that reduced vouchers from 33% to an average of closer to 20%, who took their 'earn stuff by playing games' program and ran it into the ground. This is not the GMG that most of us knew and loved. They've been maximizing their profit as best they can for a year or so now, and it's getting pretty bad.
CDPR can absolutely choose who to sell their products to. If they don't want to sell to GMG, they don't have to. That's within their right. It's neither good nor bad, it simply is. Producers are not required to sell to all retailers.
Which brings me to this point: GMG would never simply sell CD keys at a loss out of the goodness of their heart. You would have to be a complete and total idiot to think they would.
Furthermore, if there were someone offering Witcher 3 keys in the West at a price that GMG could benefit from, we'd know about it. There's no secret third party out there magically selling keys that only GMG has access to and nobody else knows about.
The most likely scenario is that GMG is buying keys from other regions where the game is cheaper, then reselling those keys in the West. Like, hey, I think it's something like $15 in Russia? Cool. They're making a nice $24 off of that deal. CDPR isn't getting their 'fair' cut. They're getting a drastically reduced cut intended for a market where people either pirate or buy dirt cheap.
If that's the case--and it is the most likely one--there is literally no way GMG are the good guys in this. Them not saying where they got the keys from would seem to support this. CDPR is absolutely fine.
To everyone mad at CDPR: stop getting mad at them just because they might be denying you a sweet deal.
