200M in 10 years from now?
Even after merging it with Gold they aren't even getting close to the around 50M of PS Now, and the pre-ABK acquisitions didn't help.
Is it going to help to include there ABK stuff? Yes, but not much since the other subs/streaming services will also have them (signed deals with everyone, and Ubi will handle them), minimum after some timed exclusivity.
On top of that, many people had GP or Gold as an extra for their Xbox console. But how about if the Xbox console dissapear and they move to PlayStation? They won't have GP there, and will find there's a more successful alternative.
I think GP won't even reach 100M in 10 years from now.
