It seems there's an explanation for the oddities of the Macworld keynote after all. Why did Jobs launch a new line of notebooks with, um, only one display size? It's common knowledge that Apple like to provide two or three offerings.

[H]e tells me the keynote that Jobs gave was not the keynote he had planned. Some of the speech had been cut out. Key products were missing. My source said there was some stuff, "some very, very cool stuff," that Jobs couldn't unveil because of "supply issues." "They can't get enough Core Duo (chips)," said my source. He also said that if he were me, he probably wouldn't order one of the new MacBook Pros.

I asked if there would be MacBook replacements for the 17-inch and 12-inch PowerBooks, but he said, "Oh, it's much cooler than that. Much cooler."
