Media event set for September 9, launch likely ~10 days later.
Apple to Hold Simultaneous Satellite Event in London for October iPad Unveilings
For the iPhone event, Apple sent out invitations to media in Berlin, Tokyo, and Beijing, hosting satellite launches in each country. Each event featured a video stream of the announcement in Cupertino, and it is likely the London event, which begins at 6PM local time at the Kings Place hall, will be run in a similar manner.
Along with the London stream, Apple is said to be setting up live streams for its employees to watch the event in Apple offices around the world, and the company will also offer a replay of the event on its website and iTunes after the event has concluded.
Apple did not provide a live stream of the September 10 iPhone event to employees, nor did the company provide an event stream for iOS devices and the Apple TV. In the past, however, Apple has streamed its events live to customers. For example, the 2012 iPad event was available via its website for Mac and iOS users, and there was a dedicated channel on the Apple TV. Apple also streamed its WWDC announcement to the Apple TV.
Apple has not yet announced plans to provide streaming coverage of the event to the general public for the upcoming October 22 event, but it is possible that live streaming will be available given the company's plan to provide feeds for employees.
Update: According to Gizmodo Japan [Google Translate], Apple will also be holding a gathering for members of the Japanese media.
