When you look at it, several things come to mind. The tag line says that "it's been way too long" Well here are my thoughts....
Considering that the iPhone, iPad and MacBook Pro have all had Retina displays for quite awhile now, maybe the Retina iMac will be unveiled. "it's been way too long for the iMac to not have a retina display".
It's been a very long time since the MacMini had a decent upgrade, "It's been way too long since we updated the Mac Mini, so now here it is"
Apple TV, It's been way too long since this product had a significant update, so perhaps a new Apple TV will be announced.
We know the iPad and iPad mini will be updated, Perhaps it's been way too long since they updated the internal memory boards and the new iPad Air will heve the 2MB update that is rumored.
It's been way too long since the announcement of Yosemite, and now you can finally get it.
Awhile back they "updated" the iWork apps to work seamlessly with the iOS and MacOS, well maybe they will announce the update that will bring back all the functions that were lost when they made that move. Just took longer than expected.
Then again as a previous post indicated maybe they realized the iPhone 6 Plus is just "way too long" <smile>
