It really seems like the ipad mini is the worst kept secret in the mobile scene right now. It is kind of obvious they feel threatened by Google from the Nexus line and Amazon's Kindle Fire.
I some how get the feeling that apple won't be deterred from suing other manufactures about the 7in aspect ratio even though they came later. In Germany they somehow managed to get the 7in version of the Galaxy to get banned. Just food for thought.
