Yes, box with PC edition will contain a GOG code.
Due to the size of the game, it would require an unrealistic number of DVDs. We considered using BluRay discs, but a standard PC config doesn't include a BluRay Drive, so we decided to use the next most convenient solution.
Then you may want to reconsider using BluRay discs again.
A GOG code alone in the retail game isn't the most convenient solution - it has nothing to do with convenience at all. The fact that a retail game is distributed without an optical disc, retoractively undermins the whole purpose of a retail game that is meant for collecting the game in the first place.
Just because there is people who prefer a digital download doesn't make it the "most convenient solution". That would be the case for purchasing the game from digital distribution, but these exact people won't bother with the retail version at all at this point anyway. However, the retail version then again proactively speaks for those, who want a physical copy of the game for their collection too and you're taking away the game disc from them.
The same goes for the collector's edition of the game. You offer an uniquely designed steelbook case of Cyberpunk 2077 which is simply empty without a disc. What's the purpose of that without a Cyberpunk 2077 game disc then? That's quite contra productive, isn't it? And it won't satisfy collector's because they'll miss the physical copy of the game. Thus the Collector's Edition is incomplete.
By the way, I can't speak out of the details that you guys have had in your Meetings at CDPR regarding this issue, but what I can speak of is that Blurays are the future for optical disc distribution not only because of the huge amount of disc space they offer, but also for the long-term data reliability. It already is a standard.
