Well, I would say that if you remove Xbox and just compare PlayStation to PC, PlayStation is probably on par or faster growing than pc.
That's just a guess though.
I mean, putting all that dead weight on PlayStations back, makes console look weaker than it is imo.
Don't forget the Switch, can't deny the numbers it has been doing.
Xbox might've massively fumbled but the slack was picked up by the other two console makers big time.
I think PC is growing much faster in recent years, due to emerging markets. But this would just further proves my earlier point.
We all remember the PC gaming days of mid/late 00s and early 10s. Lots of "PC Gaming is dead" rhetoric. To be fair, the market had lost MUCH ground to consoles and mobile. If PC can come back stronger than ever from such a deficit, the consoles which are still riding the high of of PS4 + Switch success are in no danger at all. Anyone saying otherwise is living in an alternate reality.
