That honour will go to an actual replacement to the larger form-factor Samsung Galaxy Fold - and there is now some evidence.
Dutch website GalaxyClub has been told that the internal codename for a new foldable phone is Winner 2 (or Win2). And that's important as the codename for the original Fold was simply Winner.
The codename given to the Z Flip, on the other hand, was Bloom - suggesting an entirely different product line.
So, while Winner 2 is hardly imaginative, it effectively highlights Samsung's expectations for the device - it will be the direct successor to the Samsung Galaxy Fold.
In addition to the Win2, a Win2 5G is also under development, which is perhaps more surprising. While the Fold came to different markets with and without 5G, by the time a Fold 2 is ready we'd be surprised if there is much need for a 4G-only handset in that category.
There are few other details at present, but we have heard previously that the Galaxy Fold 2 could come with a Note-style S Pen stylus, and could make an appearance between mid-to-late 2020.
