Reviewing all the news released through Blizzard on the main website, it has been exactly 205 days since any substantial news has been released, the last being on 10/9/2007 in the form of the 1up.com interview (http://www.1up.com/do/previewPage?pager.offset=0&cId=3163178).
Since then, we have received precisely, in reverse chronological order:
April 2008: No news.
March 2008: 2 Beastiary additions and 1 Environment addition.
February 2008: 1 Faction addition, 1 Environment addition, 1 Beastiary addition
January 2008: Beastiary launched, no further news.
December 2007: No news.
November 2007: 2 Screenshot additions, each containing 2 new screenshots. Utgarde Keep interview.
October 2007: 3 Screenshot additions, each containing 2 new screenshots. The aforementioned 1UP.com interview.
The 1up.com interview is really the Holy Grail of info to date. It has the most breadth and depth out of anything else. While it may technically be considered news, perhaps, screenshots and beastiary updates are really not what most players are looking for. In April '08, they did announce renewal of Chinese providers' contracts, which has nothing to do with the expansion's content or beta or release, just like the 10/30/2007 "news" about a WotLK Fan Site kit doesn't count either.
205 days without any news. Is WotLK vaporware? The original official announcement was released a whopping 272 days ago, on 8/3/2007. Since then, the pace of new information has actually been slowing instead of accelerating. Not a good sign.
Edit: 210
Edit2: At least the new Blizzard Store has been released! Now, we can buy all the same crap we already have, just from Blizzard instead of Best Buy! This is HUGE!
