The latest leaks concern the Quest 3, which is almost a year old, and the more affordable Quest 3S, which will be unveiled on Wednesday.

VR blogger Cezary Sobociński on X claims to have learned the following about the devices:

The Quest 3S will be available with 128GB and 256GB of storage and the two SKUs will cost $300 and $400 respectively. The price of the 128GB model was leaked a few days ago.
Meta will end production of the 128GB model of the Quest 3 in mid-November, only the 512GB model will continue to be sold.
Both SKUs of the Quest 3 (128GB and 512GB) will be temporarily discounted by 5-10 percent until the 128GB model is sold out.

The new price of the 512 GB model is not known, but there are rumors that the price will be reduced to $500 (the current price of the 128 GB model). The current price of the 512 GB SKU is $650.
