MGO3 PS4 Population?

As a PC player it would appear to me that the userbase is dwindling pretty quickly. Apparently the PS4 is the only platform that actually shows a number for how many people are playing, so I'm wondering. How many people are playing on PS4 on average for you? I mean the fact that they only show how many people are playing on PS4 speaks volumes to me already but I've never actually seen or heard a figure.
