Those look a LOT like the slow-developing keikis that I got on my Phal. schilleriana. (Only one of which has so far actually become a keiki - 6 months after growing as leaves like that, the other one still could, on its own schedule) . So maybe a keiki eventually, maybe a place for a flower spike first if mine is any indication. An adventure for sure.
Here is that old thread showing my Phal schilleriana last February
Confused - or multitasking - Phalaenopsis
The pseudo-keikis were actually well developed by then, so the "leaf" part was more like November or December.
