Today, Apple sent invitations to another announcement event next Tuesday. The message included in the invitations is: "We still have a lot to cover."
The speculation is that Apple will be announcing the next generation iPad and the iPad mini 2 with a retina display. The new iPad is rumored to possibly include a fingerprint scanner similar to the iPhone 5S. It will have the A7 chip, be slightly thinner, and include a better camera. Most of these rumors have been thrown around recently.
On top of that we will likely see more on the new Mac Pro and the launch of OSX Mavericks. The MacBook Pro will also get a refresh. Instead of focusing on the rumors, just check in here next Tuesday for any updates.
