Nicely said, but what has the combat and potion to do with graphics? The graphics in TW2 are pretty awesome. When you say "no thank you" you say you do not want graphics as impressive as TW2's in Skyrim?
He's just saying that graphics don't make a good game. They help, but when the gameplay is bad you're no better than a game with average graphics and awesome gameplay.
It really is a careful balance of material that makes a good game. Graphics matter, but they don't matter any more than the story, the gameplay, the soundtrack, etc. The Witcher 2 looks shiny enough, but I can say without a doubt that Skyrim's gameplay quality will surpass its easily, just as how no one praises Crysis for its excellent gameplay. Most games have a strong point that make them stand out. For instance, just look at the different fantasy games out there. Elder Scrolls is clearly the gameplay. BioWare games are famous for having comprehensive storylines, such as in Dragon Age 2. The Witcher 2 seems to be dominating on the graphics front. What people look for in video games nowadays is essentially an interactive movie. The kinds of things that make movies good (quality CGI, an engaging plot, proper film techniques) are comparable to the things that greatly help the quality of video games. The day of arcade games where gameplay is the only thing that mattered is gone. It doesn't matter http://www.imdb.com/title/tt0800320/, the movie can still be bad. The graphics can be amazing, http://www.imdb.com/title/tt0499549/. People have different tastes, it just depends on what you value more.
The Witcher 2 is a very good game though and I recommend it to everyone. If its console port is very successful, I hope Bethesda takes a look at their example and chooses to develop for PC first so the Elder Scrolls can be amazing on all fronts.
