LOL!
Interestingly, most graphic artists don't double as writers and other fields of development. So I don't think that resources have to be "diverted" from other (equally, if not more important as you stated) game design areas.
I chuckled at the rest of that post though. Blizzard definitely agrees with you on gameplay, and I think WoW is a fun game and looks decent - but it would be even more fun for me if it wasn't designed to run on an abacus graphics wise. On the other end, Age of Conan looks fantasic and plays like a piece of crap - therefore I don't play it because no amount of uh, eye candy can make up for the gameplay experience being poor.
So I don't disagree with you on that point at all, but the fact remains that the potential for a great experience on a PC is higher because of more inherent processing ability, flexibility, control scheme options and so forth.
As far as bigscreens go, before I went 3D I ran full HD on my television for kicks. I thought it was cool, but no PC game UI lends itself well to those circumstances. That, and despite being full HD, I just could not see things as well or as detailed compared to the PC monitor. I stuck with it a bit just for kicks but it just wasn't as comfortable and was in fact a very noticeable downgrade.
