To quote from PS Now Senior Marketing Manager Brian Dunn on the announcement:
We’d like to share an important update on compatible devices for PlayStation Now.
On August 15, 2017, we will be discontinuing the service on the following devices:
Additionally, 2016 models of Sony Bravia TVs will be discontinued on April 1, 2017.
- PlayStation 3
- PlayStation Vita and PlayStation TV
- All 2013, 2014, 2015 Sony Bravia TV models
- All Sony Blu-ray player models
- All Samsung TV models
After thoughtful consideration, we decided to shift our focus and resources to PS4 and Windows PC to further develop and improve the user experience on these two devices. This move puts us in the best position to grow the service even further.
If you use any of the above devices, we want to give our heartfelt thanks for your support, and we hope you’ll continue with us. Remember that all of your PS Now cloud game saves can easily be accessed on both PS4 and Windows PC.
If you do not wish to continue your subscription, please remember to disable auto-renewal in your account settings so that your subscription ends by April 1, 2017 on 2016 Sony Bravia TVs, and August 15, 2017 on all other devices.
For 3 months subscribers, depending on when you joined the service, your subscription may auto-renew a month or two before the service discontinuation date if you do not turn it off.
