Steve Jobs's keynote at Macworld is a lot like the president's State of the Union, only with better security. That's why it's so remarkable that there's been a possible leak on Wikipedia.
What makes it almost credible is the a) degree of detail and b) the modesty and probability of the products presented. No flying cars; just stuff like a thinner aluminum Macbook and a preview of the iPhone SDK.
Is it genuine? We won't know until noon ET tomorrow (Tuesday). In the meantime, what fun to speculate!
Update: Computerworld debunks this and other show rumors. Maybe....
