In a recent survey, PS4 games.
While Sony has extended their Remote Play function to the aforementioned third-party systems, they've never allowed it on other gaming consoles. The idea they would even consider it is rather surprising; Nintendo and Sony have been competitors for years, especially after 1991, when Nintendo surprised Sony by breaking off a deal to manufacture a t gaming system, the Super NES CD-ROM. This rift led to Sony creating the first PlayStation and becoming the powerhouse of the gaming industry that it is today, causing some to come to view Nintendo's betrayal of Sony as a tremendous business mistake, even with the success of the Nintendo Switch.
Now, it seems Sony may be considering the possibility of bridging the gap. In a recent survey leaked by Xbox systems, or in using Xbox controllers with other systems. A connection between Xbox and PlayStation would also be surprising.
Survey-takers are given a five-point scale of response that ranges from "Not at all appealing" to "Extremely appealing." According to the email sent by Sony which invites players to take the survey, it lasts about 25 minutes. YouRedditHereFirst describes the survey as lengthy, but considering the wealth of potential information contained within, the length seems more than worthwhile.
Sony has yet to make any comments about the results of the survey, and players likely shouldn't hope for any real developments any time soon. The possibility of Remote Play on Nintendo Switch and Xbox is purely theoretical, and it may never be anything more. Still, if Sony is entertaining the possibility, even if it's nothing more concrete than a survey question, this could mean big things for the future of video game connectivity.
