In non-WoW Blizzard news, the Starcraft 2 beta will start this summer and will be the "final" phase of development for that game. The new Battle.net interface will be tested then as well, so keep an eye out for that. And Blizzard expects big things there in China also -- NetEase, the company that will now be handling Wrath's launch, is already set up to run both Diablo III and Starcraft 2 out there, so it'll all be under one umbrella.
In short, there's no really bad news from Blizzard, but no really great news either -- the best news to come out of the call is that even in the slow economy lately, Blizzard is holding steady. Not a bad thing at all, but we probably won't see any spikes in player interest in Blizzard or WoW until they announce what's next on the content plate, whether that be at BlizzCon or before.
