In brief:
StarCraft: Legacy is online.
BlizzForums will be online tomorrow.
Details will be provided tomorrow (we want BlizzForums to be online as well). Server hardware is being replaced, so this estimate may be sooner or later then reality. This experience has been as frustrating for us as it has been for you; we're sorry for the disappointment, and we're thankful for the Community's support.
BlizzCon 2008 coverage will be updated and released tomorrow. This weekend will feature articles from the staff who attended the 'Con.
BlizzCon 2008: In Review will be used (or republished) as the post.
