The concept art focuses on a giant mobile instrumental monstrosity tentatively called the "no man band," as well as a nice archery range and some drawings of the "Asura Gate." The subject of the two screenshots is an open-air theater, complete with painted sets.
Guild Wars 2 is headed exclusively to PC "when it's done."
Guild Wars has some of the most refreshing designs in fantasy games. I love their artwork too.
i find arenanet's artwork to be the best in the video gaming industry.
