With tablet sales slumping, rumors of an ‘iPad Pro’ still circulate. The 12-inch tablet is widely speculated on, but we’ve still not seen anything close to a finished product. There have been ‘dummy’ models photographed, and cases surreptitiously snapped, but nothing suggesting anyone has a working iPad Pro anywhere on Earth (except maybe Cupertino). In the latest turn of events, we’re getting another look at cases for this iPad Pro. The difference? this time it’s a video, not sketchy pics from who-knows-where.
