With iOS moved to fall, the MAC will be back!!!
My predictions....
March will see a return to Software announcements. Something Apple has long since been accused of ignoring of late.
I think new MacBook Airs / Macbook Pros and that finally about time it was sorted "Mac Pro" refresh that pro's have been crying out for, for far too long.
New Mountain Lion updates and/or 10.9 information and of course some pro-app announcements to go along with it
Aperture 4,
Final Cut Pro XI
Logic Pro 10
iWork 13
New iLife applications.
Those happening in the end of Q1 2013 going into Q2 2014 will keep most people more than happy including the stock market / shareholders.
There was a time 'before iPads' when Apple Mac's were the focus. Apple could re-brand 2013 as year of the Mac!
