I knew he stepped down but I didn't know he was starting a new venture already. Is there any indication what the new venture is about? The site doesn't say much unfortunately.
Per the site and his instagram [0], it's an AR thing of some sort. He was playing around with a North Star prototype [1] on stream a few days ago [2]. But it's still very early–if he actually sticks with this project I imagine it will be at least few months before anything substantial is announced.
