Apple has not announced plans to webcast Apple CEO Steve Jobs’ keynote speech at Macworld Expo, Tokyo. However, the company has created a Web page to release news from the event.

Jobs takes the Expo stage at Tokyo’s Big Sight Exhibition centre (illustrated) at 9:30am, Thursday March 21. That’s the equivalent of 12:30am in the UK. Big Sight opened in April 1996 and offers 230,000 square feet of exhibition space.

No new Macs yet Apple product manager Greg Joswiak announced recently that Apple is “not planning to introduce any new CPUs at Macworld Tokyo”. No guidance has been issued regarding the company’s software or digital hub products – the iPod, for example.

Some rumour-site reports claim Jobs will discuss the problems the company’s faced in shipping its new iMac in quantity. It’s feasible the company will discuss Mac OS X, possibly welcoming the recent announcements of several key applications for the OS, including Adobe Photoshop 7.0 and Steinberg’s Cubase SX.

Despite analysts’ concern regarding iMac supplies, Apple’s shares held well yesterday, climbing $0.11 (0.44 per cent) during the day’s trading to close at $24.85. They climbed to $ 24.92 on the extended trading market.
