March 24th Event to Focus on Software?
Sevenmac has now received from an anonymous information source a report that the March 24th event should revolve exclusively around software. More precisely, Apple's video Pro Apps should receive updates or see new versions.According to Sevenmac, a new version of Final Cut Studio currently exists as an internal beta. The beta version, however, is reported to be buggy, which could force Apple to delay the special event by several weeks. No additional information on other possible software updates for the event are given. It would be unusual for Apple to hold a standalone media event for software updates alone, though further announcements or demonstrations of Apple's upcoming Snow Leopard could conceivably warrant an event.
Rumors of a March 24th event began circulating just days before Apple released new iMacs, Mac minis and Mac Pros. With that revamp of Apple's entire desktop line having occurred last week, the March 24th rumor was presumed to have been unfounded. This latest tip, however, revives speculation that Apple may yet be planning more releases in the near future.
