The firm revealed yesterday that a new iPad, the 'iPad6,8', had turned up in its database. They haven't shared data on the screen size or other technical details, but they did note that its screen resolution was 2,732 x 2,048 pixels.
That matches closely with previous leaks and rumors about the iPad Pro, including the code references in iOS 9 that pointed to an onscreen keyboard designed to fit a screen with those dimensions.
There's a lot of speculation surrounding the new iPad, including suggestions that it would have a pressure sensitive touchscreen, but (for those of us who don't follow it closely) it's hard to tell which is real and what is the result of fanboy optimism.
In related news, AppSee's logs also showed data on two new iPhones tagged with the labels “iPhone8,1” and “iPhone8,2“,. These are probably the soon-to-be-revealed new iPhone 6S/6S+, but these are much smaller news.
