It is too late for predictions, we have read all the silliness for months and there are a few known facts concerning OS X and iOS 7 with some interesting banners being displayed at the Moscone Center. These, and the thinner fonts have all been analysed to death by those who do have some ideas about what happens at Apple and by an awful lot who do not. The truths will be with us in just about 24 hours from now.

In the meantime, it may be a good idea to set up information sources for those who are going to follow the keynote speech blow by blow. That in itself has caused some speculation: who is to speak? For sure, Tim Cook will open the show and probably sum up at the end. Phil Schiller is the main marketing man and is favourite to take up most of the slack especially if there are some new Macs. MacBook Air, Mac Pro and perhaps MacBook Pro have all been mentioned, especially with stock levels falling with some.

The MacStories Twitter feed had an interesting image suggesting Craig Federighi could present information for both iOS 7 and OS X, but I think this is a little stretched. The "?" over Jony Ive's photo was interesting: would the usually-silent Ive take the stage? Reactions from the audience would be interesting.

A number of sources are providing live blogs of the event and I have a list of what I have seen so far (in alphabetical order). I have added two more sources to the list and fixed the order:

• 9to5 Mac

• Ars Technica

• Engadget

• Gizmodo

• iMore

• MacStories who also have a neat little link that provides a reminder about the event via Passbook on the iPhone

• MacWorld with Dan Moren and Jason Snell;

• SlashGear

• The Next Web who like MacStories also have a list of local times

• Today's iPhone

• TUAW: The Unofficial Apple Weblog

I will also be looking forward to the video of the event that Apple is expected to post shortly afterwards.
