More megapixels, same optical zoom skills
Specifically, it's possible (although still far from etched in stone) that the S24 Ultra's secondary 10MP telephoto lens with 3x optical zoom functionality will gain no less than 40 megapixels while keeping the zooming capabilities unchanged for the S25 Ultra.

The ultra-wide-angle lens on the S25 Ultra's back, by the way, could also jump from 12 to 50 megapixels, while the main camera and the 5x optical zoom-supporting periscope telephoto lens are expected to stay largely unchanged at 200 and 50MP respectively.
All in all, it's hard not to get excited at the sight (and the thought) of a 200 + 50 + 50 + 50MP quad rear-facing camera system. Of course, impressive megapixel counts are not always representative of a remarkable real-world photography experience, but the Galaxy S24 Ultra is already undoubtedly one of the best cameraphones in the world with a 200 + 10 + 50 + 12MP setup, so there's no way its upgraded sequel will not prove to be even better, both in theory and in practice.What other major upgrades should we expect?
That, our gentle readers, is a million billion-dollar question Ice Universe is in no position to answer at the moment (either on Weibo or X) with anything other than educated guesses and largely unfounded speculation.
If you don't like that sort of thing... then why did you bother clicking on this story in the first place? After all, the Galaxy S25 series is almost certainly still roughly eight months away from an official announcement, which means Samsung itself may not have decided on the Ultra's final design or specifications yet.
