Their Quest Pro is getting a similar treatment. It also has eye tracking, and better displays than the Quest 3, aside from resolution. They are also releasing a depth sensor for the older model's front-left USB port as their current push for AR requires it, though the Quest 2 and Pro will not have the same pass-through image quality as the new Quest 3.
The integration of eye tracking and improvements in display technology are common advancements in VR headset development. Eye tracking can enhance both user experience and heardle (https://heardleunlimited.io) performance, allowing for more natural interactions and potentially improving rendering efficiency.
