This has been the case for years, when are people supposed to 'inevitably realize' this?
I agree that it's not a given that eventually people will "see the light" and get GP.
Nevertheless, the more value MS adds to the service and the more exposure that Forza Horizon, Sea of Thieves, Indiana Jones, Gears of War (probably coming to PS) etc... get on rival platforms, the more likely that some people get the GP bug.
We all know the reasons to get GP, but here are some reasons not to for Joe gamer:
1. I only play Call of Duty (or insert X game here) (my older son falls into this category)
2. I want to own my games (many people here on this forum)
3. The PC app is crap
4. I can't get GP on my hardware
This list probably limits GP to less than 20% of the market. Reports suggest 35 million right now, which is probably only 10% of the market. So there's room for growth.
If they fix #3 and more people become ok with #2, then maybe the upper limit could grow to 30% of the market or something like that. That's over 100 million subscribers, but they have a lot of work to do to get there.
The release cadence is getting pretty good and IMO very attractive to the hardcore gamer, since October:
Ara
Age of Mythology
Call of Duty
MS Flight Sim 2024
Indiana Jones
Ninja Gaiden Black 2 Remaster
Avowed
33 Immortals
Expedition 33
South of Midnight
Doom DA
Tony Hawk 3&4 Remaster
Towerborne
Ninja Gaiden 4
Oblivion Remaster (rumored)
That's a pretty ridiculous lineup for 12 months and that's without adding in most of the 3rd party stuff. I believe this lineup will get GP to at least 40 million subs. We'll see....
