Yeah compared to e.g. Apple’s ‘here’s our new iWidget 42 pro, you can buy it now’ it’s at best disappointing.
The first of it's type AR/VR hardware has, understandably, a longer release cycle. Also, Apple announced early to drive up developer interest.
Apple aggressively keeps products under wraps before launch fires employees and vendors for leaking any sort of news to the press .
