I think an interview with Adam Badowski is more than some claim and FUD
Well, what did Adam actually say? He said that there won't be better textures and models on PC at release because they apparently don't have the manpower and time to do better ones just for PC on time. That's indeed sad since a lot of other developers (even the always crucified Ubisoft) offered better textures on PC if you have the respective hardware, like Shadow of Morder, AC Unity or Dragon Age Inquisition.
But that has obviously nothing to do with a downgrade, simply because there never existed better assets only for PC in the first place. If there existed better assets there would be no reason to not use them and there would be no reason for Adam to claim that they don't have time to create better ones. So there might be no "update" here (textures and models) but there is also clearly no "downgrade".
What Adam also clearly stated was that in an huge open world game with different regions with different color palettes, different weather conditions, different hand made environments, , different vegetation, different daytimes and so on you cannot simply compare two different scenes and make any graphical claims on that comparison. Just because one scene seem to offer "worse lighting" for example doesn't automatically mean that there is any downgrade on purpose going on. It's probably the very same graphical version, just under different conditions mentioned above. And then you can even alter the same graphical version with simple tools like bloom, blur, color changing, sharpness enhancements and so on. That's what many people do for their PC games with for example tools like SweetFX or just by using different ingame settings. For example, in the SOD trailer the sharpness was really exteme, maybe two extreme (just look at the vegetation) while in the latest gameplay vid some blur was visible. Again, that isn't an indication for a possible downgrade, it's just a difference in settings and scenes.
So, nothing what Adam said is any indication for a possible downgrade. The mods pointed you to another thread if you want to talk about the topic whether PC should have better assets than the console version and that's totally understandable imo.
