You joke, but 4 to 5 would be the right number if they could magically work out all the engineering problems.
The biggest problem for 2-fold is that if you start with a a standard widescreen 9:16, unfolding gets you 18:16 -- a glorified square. It's nice for content that doesn't care, and is awesome for tankobon comics which are 7:5 and painful to read on a normal phone. On the other hand, the unfolded version doesn't get you much extra space when viewing standard widescreen video -- it's a small improvement but the vast majority of the extra inner screen area gets letterboxed. A third fold would do a lot to fix that.
Except that phones are typically taller than 9:16. For example, the Pixel 9 and 10 folds are 9:20. (and then the inner screen is 1.04:1). That means you need a 4x fold to get to 16:9 when unfolded, and then a fifth fold would get you approximately the original phone aspect ratio.
