According to KGI analyst Ming-Chi Kuo, the iPhone 8 isn’t expected to enter mass production until October or November, which means the device will be available in very limited quantities this holiday season—if at all. Kuo’s report follows up on another rumor claiming the iPhone 8’s release would be pushed back by a few months.

Apparently, the delay is due to the “significant hardware upgrades” in store for the iPhone 8, including an OLED display, custom A11 chip, and revamped design.

Kuo believes the delay will have a big impact on Apple’s 2017 sales as people wait for the iPhone 8’s release. Apple is still expected to introduce an iPhone 7s and iPhone 7s Plus, but it’s the company’s tenth anniversary iPhone that consumers are most anticipating.

Numerous report suggest the iPhone 8 will take a lot of inspiration from the Galaxy S8, which started hitting stores last week. In addition to a redesign and the inclusion of an OLED display, Apple’s device may also feature Touch ID beneath the display, which could be another reason for the delays.

If indeed mass production for the iPhone 8 isn’t slated to begin until October or November, finding one in time for the holidays may be next to impossible.
