Wait...You mean a tech company is already working on their next product?! WHAT?! THIS IS AN OUTRAGE!!! I thought with every release of a product the whole company went on a 3 month vacation!! The next thing yours gonna tell me is the Microsoft is working on Windows 9!!!

Either it is a PR approved 'leak' or someone played with the header.
