You really think so? I think the HD 2k textures look dreadful. The textures just all seem to have loads of grain and high contrast, okay the resolution looks higher because of all the spots and scratches, but it looks bad to my eyes. The HD DLC just looks much smoother and realistic to me and also doesn't seem to have any particularly jarring texture transitions that there seem to be on HD 2k.
The real beauty of all this is that we win. More choice = more Charlie Sheen.
