Yup, PS4 may look like that, but the article still made false statements that, based on their track record, were probably clickbait. They know PS4 owners are wanting more information, so decided to make some up.
"The Witcher 3 Old vs New Build 1080p Screenshot Comparison Shows Massive Visual Improvements – Could be PC vs PS4" - Could be, but it isn't.
"so it is very much possible that the new gameplay trailer is from the PC version of the game, and the graphical difference...is between the console and PC versions." - No, not possible, as it's already well-documented that the earlier one was also PC.
I'm going to lock this as it's likely to mislead others into thinking that the article is correct. If you want to discuss further maybe continue in the main Discussions thread?
