Heads up; there are even more StarCraft II shots this morning, this time "revealing" (even though we've seen glimpses of them before) the third Zerg faction - which naturally looks colourful and lovely.
There's also a shaky-cam Zerg trailer over on YouTube, but you'll have to bare with us while we get our hands on the proper direct-feed one.
Yesterday Blizzard released a community-led Q&A session in which the developer answers questions on units, the possible inclusion of potential bugs (?) and promoting the sequel as an eSport. It's worth checking out.
