Mass shipments of Apple's upcoming augmented reality and virtual reality headset, expected to be released next year,  may be delayed until the second half of 2023 due to unspecified "software-related issues," according to a information shared Sunday by noted Apple analyst Ming-Chi Kuo.

Shipments of the much-rumored AR/VR headset are still expected to begin in the first half of the year, but not at the same volume previously predicted, Kuo wrote in a series of tweets.

Kuo had previously reported that the iPhone maker was looking to ship 1.5 million units of the face-mounted device in 2023 at a price of up to $2,000. Kuo reported in August that Apple was expected to announce its headset during a January 2023 event and that the company has already presented the device to board members.

Apple didn't immediately respond to a request for comment.

Apple's first headset is expected to be pricey: a rumor last year suggested the company's first VR headset would be "far more expensive" than other VR products that come in under $900 -- though it's unclear if it would be more exorbitantly priced that the $1,500 Meta Quest Pro.
