From the looks of the artwork, the zerg have evolved. There is a concept art for the Hydralisk, and it now has multiple scythes, and is way meaner looking.
Something tells me the Zerg will be more of a threat than before.
I want to see what they are doing to my favorite unit..the Goliath. That thing was a monster in the first game. A group of Goliaths could destroy almost anything on the ground AND the air.
