Meta CTO Says Quest 3 Announcement Timing Had ‘Nothing to do with Vision Pro’
According to Meta CTO Andrew "Boz" Bosworth, the announcement of Quest 3 was not influenced by Apple's foray into XR. Bosworth explained that the decision to announce Quest 3 early was made well before they knew about Apple's plans. He mentioned that the timing of the announcement was to capture the full holiday season and allow people to plan ahead. Bosworth also shared his thoughts on Apple's decision to have an attached battery pack for the Vision Pro headset and how it may impact Meta's roadmap.
