Say what you will about him, but his predictions have proven accurate so far: ML has made very suspect claims to investors and the public and ML's technology offers little innovation over the status quo, based on the information available so far.
So far it's the only headset coming to market that contains all of the following: Standalone, eye tracking, variable focal planes, hand tracking and a 6DOF controller, and a significant increase in FOV over Hololens (roughly 55 degrees to Hololens' 35). There are other AR headsets announced that may have a huge FOV but are tethered to a PC and have questionable visuals. Really, once Magic Leap is out it will be quite unique, and not just because of the tech it packs compared to the competition but because they've also been building content from their first party studio as well as numerous gaming and productivity partnerships.
