Seeing the latest offering from Microsoft called the Xbox Game Pass, it seems Sony was pressured to double up on their offerings. The PlayStation Now service will now allow for streaming of PS4 games later this year.
At the moment, the service is still testing out PS4 games in a closed beta of sorts, with active PS Now subscribers being sent invitations. It seems they will be cutting off support for all devices other than PlayStation 4 consoles and PC systems in order to make this happen.
While the service may not be available in all its glory for the Middle East region, you can bypass this restriction by creating a US or UK PSN account.
