IDG World Expo is promising the largest ever Macworld Conference and Expo next week.

The show, which occupies over 100,000 square feet of space at New York's Jacob Javits' Centre, hosts nearly 250 exhibitors and should see dozens of new product announcements from the Mac industry, the organizers claim.

The show runs July 15-19, with a keynote speech from Apple CEO Steve Jobs scheduled for July 17 at 2pm (UK time). The keynote speech will be Web cast by Apple.

New products promised at the show include offerings from Extensis, El Gato Software, Pixologic and Stone Design.

New York Times columnist David Pogue, will be at the show presenting "Toward Mac OS XX". This is a seventeen-year history of the Mac OS, taking a look at Mac OS X and leaping forward to imagine what Mac OS will be like in 2020. This presentation takes place July 18 at 9.30am (local time).

The show also features a digital art exhibition, gamers' area and special interest areas.

However, there are several high-profile absences from this year's show - for example, Adobe and Macromedia won't be exhibiting there.
