It certainly has been odd watching Apple this year. Normally the company announces something significant every few months, but in 2013 they've gone (almost) completely silent. The last product release of note was the 2012 iMac, which was announced in October. So that's seven or eight months of silence.
Something has been brewing at Cupertino, and I'm looking forward to tomorrow. Between this and E3, this week is like nerd Christmas.
