http://diablofans.com/forums/picture.php?albumid=55&pictureid=915&thumb=1Blizzard recently updated Diablo3.com with a few new screenshots. It appears to be a few new ones featuring Act II locations and the characters dealing out their skills on their enemies, as well as an updated blood texture that departs from the vibrant monochrome of old (see left).
http://diablofans.com/forums/picture.php?albumid=55&pictureid=916&thumb=1Could these serpentine poker-wielders be the revamps of the Claw Vipers of Diablo II and Diablo I (see right)? The Witch Doctor's pyrotechnics even seem more appealing for some reason, as does his body animation, or maybe we're just reading too much in to these images. A quick view of a cached version of the gallery reveals as many as twelve of the images are new, so go and see for yourself by checking out the rest in the screenshot gallery on the official website.
Thanks to snillum101 for the heads-up!
