Thanks to u/YouRedditHereFirst on r/PS4:
I just took a survey for Sony regarding their Remote Play and there were some interesting questions that possibly hint at upcoming features.
- Using Remote Play with a PS4 not connected to the Internet.
- Playing Remote Play on a Switch, AppleTV, AndroidTV
- Hiding unused controls for the game to allow for more screen real estate
- A slim/portable DualShock controller for portable gaming
- Exclusive maps/accessories for Remote Play
- Customizable button layout
- Connecting other controllers (Xbox) and mouse/keyboard
- Offline Remote Play
- PS1 and PS2 games
- Parental controls to allow for multiple users to use Remote Play at the same time.
I took some screenshots of one section of the rather lengthy survey. There were several questions about PS1 and PS2 games, as well as being able to adjust video and sound quality to help with any lag.
