I develop small games with UE4, the same engine they're using for this. If they do the graphics settings right, it actually scales way down and you can run it on mid-end systems
and how many MOBAs can you play on ps4? Last time I checked, the number was 0.
games like this and Battleborn will be the first. and if you're a PC gamer, they are still at least doing things a bit differently than most traditional MOBAs.
