New info: IncGamers reports on plans for DLC as well as trial versions of the game, which will be released after the game, not before, and they also report on DRM (even though Blizzard seems relatively unconcerned about piracy) saying the game will require a Battle.Net account and an online verification to install, but players will not need to be connected for solo play after that. Also, VG247 reports there will be no co-op campaign and that the game has a new logo. Finally, Shacknews discusses classic StarCraft units that will be making cameos in the sequel.
As for media, There's a new StarCraft II: Wings of Liberty story/gameplay movie on the YouTube (mirrored on ActionTrip and AtomicGamer) and a StarCraft II "Old Rivals" cinematic trailer on GameTrailers as well as StarCraft II screenshots on Computer and Video Games.
There's a Q&A with Blizzard’s Rob Pardo on VG247 and StarCraft II Developers Talk Single Player on IncGamers (highlights: Blizzard: PC Gaming Is NOT Dying! and Metzen Prefers StarCraft over WarCraft). There are also hands-on previews of the game on 1Up, BlizzPlanet, Destructoid, IncGamers, IGN, Shacknews, and VG247.
Finally, the LAN in Starcraft 2 Please Petition now contains over 100,000 signatures (thanks VG247).
