Witcher 3 - CD Projekt tackles downgrade issue [Update]

Apparently there is some kind of controversy about the graphics in the commercial release of The Witcher 3 not matching a promo video from a couple of years ago. What do the people at CD Projekt have to say for themselves? They've talked with Eurogamer:

Eurogamer: Did the console versions restrict the PC version?

"If the consoles are not involved there is no Witcher 3 as it is," answers company founder Marcin Iwinski. "We can lay it out that simply. We just cannot afford it, because consoles allow us to go higher in terms of the possible or achievable sales; have a higher budget for the game, and invest it all into developing this huge, gigantic world.

"Developing only for the PC: yes, probably we could get more [in terms of graphics] as there would be nothing else [...] But then we cannot afford such a game."

Studio head Adam Badowski confirms that the trailer shown at the VGX tradeshow was captured PC footage of the game as it existed at that time, but that the rendering system was changed after the creation of the trailer, partly to avoid the demands of dynamic lighting in a huge open world.

Also , Eurogamer reminds us that:

a big patch with 600 changes - including improvements to graphics and graphical settings - was sent to certification today (Wednesday 20th May), and will take between five and seven days to clear. 

In addition, CD Projekt Red will patch the game to allow editing of .ini files on PC, to push graphical settings even higher. You will be able to tweak grass and vegetation density, post-processing effects such as sharpening, and draw distances.

"And we think about some other tricks but we need time," Adam Badowski says.

Update: It turned it this was a misunderstanding. Said patch was the day one update.
