Xiaomi has started to hype the 13 Ultra's impending launch with some juicy details on its rear camera mega-hump, and how it may be an upgrade on that of the preceding 12S Ultra. Both devices will have the same 1-inch main camera - however, the Sony IMX989 will be augmented by no less than 3 additional 50MP lenses in the newer model. Furthermore, they will be exclusive to the 13 Ultra on their debut.
