It's unique in that there hasn't yet been an advanced 30fps PS4/Xbone game ported to Switch.
Out of curiosity which more demanding ones do you think would be better suited?
Sure but the game runs on UE4 and considering Switch supports UE4 and that the engine is scaleable (I believe?), this isn't exactly an overly difficult port to do.
Something like RDR2, or even not open world would be a better test case. Anything UE4 is pretty much fair game for Switch and hardly surprising if announced for the device.
