I thought most of them were pretty rubbish this year. 3D Realms one is always funny 'look for news of out new game soon'. One that I'm not sure is a joke was a article I read that stated that Microsoft were allowing favoured status companys to develop XBox next games for free, which I haven't read anywhere else. I reckon it could be true, and shows a lot of courage from Microsoft.
Bungie had something about a Pimps at Sea movie being in the works (it seemed like it orignated somewhere else and they were just talking about the rumor, or something.) Not quite as good as their usual update, imho. Still, really looking forward to the movie. And the game!
