Now, to the live stream...
Apple has not confirmed a live stream yet, so I don't think they are going to have one. Of course they are going to put the keynote up on their events page some hours later, but that isn't quiet the same..
Although it is not likely that they are going to live stream, there are some clues that are indicating a possible live stream.
The fact that Apple has live streamed from the location, where the keynote is being held tomorrow, before and that they are live streaming the event in London for journalists to watch, make it a little bit more likely that they are going to live stream the 22 October event.
If they decide not to, there are always going to be a live update in the form of text, but that isn't quiet the same, is it?
Lets hope they do live stream it!
