Starcraft 2 Zerg preview vids, screenshots, and new unit info is now available.
Starcraft had a few units that were only minimally useful, and rarely made an appearance in games. Blizzard appears to be focusing on a smaller number of highly useful units for Starcraft 2. Marginal abilities like infesting a Terran base have been expanded (infest any structure; infest using a unit that can move while burrowed– and that same unit has Dark Swarm). The Nydus Canal is gone, replaced by a mobile version called the Nydus Worm.
I vastly prefer the Starcraft philosophy over the Total Annihilation/Supreme Commander philosophy, so I find the Starcraft II development incredibly exciting. Top-notch RTS games are released pretty infrequently, and good games in the Starcraft vein are truly rare.
