The PlayStation 4 version of The Elder Scrolls Legends is in question due to Sony's stance on cross-play. Bethesda's Pete Hines told Eurogamer that cross-play and cross-progression support is essential for Legends, and with Sony not allowing cross-play, that presents a problem.

"We continue to make our case for 'this is how it needs to work' and 'this is how it needs to function,'" he said. "But we are moving ahead with the assumption that any platform we release it on must support cross-progression and cross-play. I am aware of the conflict that arises given that statement but we are continuing to work on it."
