I bought an Xbox One X just for this game. Couldn't wait for the PC version - they haven't even announced it - since the PC version of GTA V was delayed by 18 months, I'm not waiting that long to play this. RDR was one of the best games ever; probably the last game I played on the Xbox 360 (other than GTA V).
If they do bring this out on the PC (I'm really hoping they do), it will be one of the greatest games of all time. Those panoramic views in the trailers look so amazing - imagine that in 8K!
