|Unusually for Apple, it did its own leak this time.|
As predicted there's little new about the two devices to get excited about. They look pretty much the same as the outgoing models - although I'm guessing that Apple will once more have reduced the depth of the device, in its crusade to make every device thin over every other possible feature.
Other than TouchID there's nothing new to see. There are hints in the documents that new cameras may debut, although people who take photos with tablets are generally beyond help it may assist those who use their iPad as a quasi-document scanner.
So will you be upgrading? I really can't see any compelling reason to do so.
