Well in it can work since in multiplayer the replays r recorded after the match and single becuz it won't interfere with anyone

Lol, put it like that and they definitely aren't implementing it. As far as I remember right now, they aren't changing anything that would break replays.
However a skip command would definitely would be useful. Most people would probably never use it though. It's much more satisfying to watch the entire replay.
Still ~Supported.
