Meta (Facebook) is announcing the Quest 3 mixed reality headset for a second time and has confirmed that it will be available on October 10 starting at $500. Meta seemingly got a little anxious this summer when it pre-announced the Quest 3 headset a few days before Apple's announcement of the Vision Pro. At an event this week, Meta provided more details on the headset but still tried to hide the fact that Quest 3 uses conventional LCD displays with subpar picture quality.
