The two parties are engaged in active discussion regarding the organizers intention to move the east-coast Macworld Expo from New York to Boston in 2003. Apple objects to the move.
Macworld Expo San Francisco takes place at the Moscone Centre from January 6 to 10. Apple CEO Steve Jobs will deliver the keynote speech on Tuesday, January 7 at 9am (5pm, UK time).
A second Apple keynote this year will feature Phil Schiller, Apple's senior vice president of worldwide product marketing. He will proffer a presentation on "The Power of X" on January 8 at 9.30am (5.30pm UK time).
"We'll be there, and we're fully committed to making Macworld San Francisco a great experience for everyone," said Jobs.
IDG World Expo president and CEO Charlie Greco said: "We're thrilled with Apple's enthusiastic support of Macworld San Francisco 2003, and look forward to another record-breaking crowd."
