Oculus Quest is coming, tagged at $399, without any need to be connected to additional devices.

Oculus Quest
You won't need an extreme gaming computer worth over $2000 besides the VR goggles, which by itself usually goes for $349~$499.
The new Oculus Quest doesn't require your headgear to be connected to a nearby computer. It also works with wifi and comes with a higher resolution screen for extra immersion.
Weighing only 100 grams more than the default VR headset, the Quest is comfortable even though it carries an onboard video card. It's made for a more casual experience, ideal for games with slower pace. This is because all of the computing is done in the Quest itself.
It offers a gratifying experience with a lot of freedom. Even kids and adults who are not used to the gaming world would be able to greatly enjoy this experience.
