I'm not sure if Apple did a good job at keeping secrets, or whether there isn't anything to keep a secret about? We're expecting new software, but that's easy for Apple to keep under wraps as it doesn't really have to be used outside Cupertino, unlike manufactured products like an iPhone. Nothing abnormally secret there. We're expecting new MacBooks, but the rumour is a move to Haswell, which would only be a spec bum…
What do you mean by this? You listed the things that we do know, then said nothing about those things are abnormally secret.
