My first guess would be that they will be able to see each other because light doesn't need to follow a radial geodesic.

The only way to make sure is to write Schwarzschild metric, find the path of the two falling observers (you can assume radial geodesic) and then find all the possible null geodesics that cross a point of the trajectory of observer 1 and see if any of them also crosses the trajectory of the other observer.

What is our current "best guess" about how to observers that entered a black hole on opposite sides would look to each other once they crossed the event horizon?byWittyUnwittinglyMy first guess would be that they will be able to see each other because light doesn't need to follow a radial geodesic.
