Samsung's next bendy phone to land as Galaxy Z Fold 2, is a bi-folder in the cards?

We are just learning that the OG Samsung Galaxy Fold successor will not be just cold the Fold 2 but actually might be named the Z Fold 2. This would immediately put it in one series with the Galaxy Z Flip despite the drastic design differences – after all, the Flip is a horizontally folding clamshell, while the OG Fold and the Fold 2 bend over a vertical line in the middle of the display.
At the time, the leaked teasers for the Flip showed two phones, upper half next to lower half, worthy of a Zoro sequel poster. That seems to be a deliberate strategy, and could either hint at future bi-folders, like the one Xiaomi demonstrated, or simply denote the freewilling design nature of Samsung’s foldable handsets.
