Vivo has scheduled its X500 series launch event for September 21 in China.
The company has confirmed three phones: the X500, X500 Pro, and the new X500 Pro Max.
Vivo is skipping the X400 name because the number four has negative associations in Mandarin and Cantonese.
The phones will not be the only products at the event, as Vivo is also expected to introduce the Watch 6 and a new pair of ear-clip headphones.
Several details have already been shared ahead of the launch, including camera specifications, chip information, and official images.
Taiwanese actor and singer Jay Chou, who was involved in the X300 Ultra's marketing campaign last year, has also been seen filming an advertisement for the new lineup.

The standard model will be the compact, easier-to-hold option in the family.
It features a 6.59-inch 1.5K OLED display and a large 7,500mAh battery, backed by 90W wired charging and 40W wireless charging.
Vivo will offer it in four color options at launch.
On the camera side, the X500 carries over the main sensor from last year's X300 Pro, a 50MP 1/1.28-inch Sony LYT-828, paired with Zeiss gimbal-level stabilization and a CIPA 5.5 rating for shake reduction.
The telephoto camera steps up a bit, borrowing the same 64MP Sony LYT-610 sensor found in the X500 Pro, complete with 4K 120fps slow-motion support and its own CIPA 5.5 stabilization.
It is also confirmed to work with a 200mm teleconverter accessory.
As for power, the device is likely to be powered by the new Dimensity 9600M chip that MediaTek unveiled in an event just today.
Vivo X500 Pro and Pro Max
The X500 Pro gets a more advanced telephoto camera. Vivo has confirmed a 64MP Zeiss APO super telephoto lens with an 85mm focal length.
The camera uses the same BluePrint design as the Pro Max, but with a different sensor and pixel arrangement.
Vivo says the lens itself is a direct evolution of the APO work it first introduced on the X100 Pro, now shrunk down to fit without the size constraints that limited that earlier design.
