343 have mentioned that 'they would like to put Halo MCC on PC' (don't quote me on that), so maybe within a few years after Halo 5 or sales drop. It wouldn't be surprising as XBO exclusives Dead Rising 3 and Ryse: Son of Rome have come to PC, and there have been rumours about Sunset Overdrive and Forza Horizon 2.
