Xiaomi launching Mi Mix 3 on October 25

On August, Xiaomi confirmed that they will release the 3rd phone in their Mi Mix series. The date was not confirmed at that time. The company did, however, make an announcement of the launch of their new flagship device. Mi Mix 3 is set to hit the market on 25th October.
The phone will have a sliding camera as per the teaser by Chinese social media Weibo.

The sliding mechanism of the Xiaomi Mi Mix 3 is probably the same as Oppo Find X with a notch and 100% screen-to-body front with a sliding back. A video on YouTube is claiming Mi Mix 3 has a sliding feature like Oppo Find X:

Xiaomi Mi MIX series has always offered a very high screen space. We can expect to see a button specially made for controlling the AI features. What other features the phone is going to have is still a mystery.
Xiaomi has already started teasing the smartphone on social media. Donovon Sung, Global Spokesperson and Director of Product Management for Xiaomi, has posted an image on Twitter showing the upcoming Mi MIX 3 device.
