The iPhone 6S and the next-generation may be the most anticipated devices that’re expected to be unveiled at Apple’s big announcement event tomorrow, but let’s not forget that we’re expecting a couple of new iPads as well, the most notable of which is the long-rumored iPad Pro, which is supposed to Apple’s biggest tablet to date. We won’t hear anything official on the device until tomorrow, but for those of you who lack that kind of patience, 9to5Mac has released a fully detailed report on the 12.9-inch device ahead of the event.
