Microsoft and Nintendo are rumored to be coming together in order to publish more Xbox games on Switch. The collaboration would involve both direct ports and a Switch app allowing for Game Pass, the Netflix-esque subscription service for video games, to be available on Nintendo's console.
According to the YouTube channel Direct Feed Games, Microsoft is specifically looking at publishing Ori and the Blind Forest, which is currently an exclusive for Windows 10 and Xbox platforms, on Switch. This has been corroborated by Game Informer, which spoke with its own sources to confirm that Game Pass will be arriving on Switch as soon as this year.
Moreover, VG247 has heard "similar whispers" about other games, including Super Lucky's Tail. The game's website also says that other games published by Microsoft are "not out of the question."
Project xCloud, the cloud-based game streaming service Microsoft showed off at E3 2018, could be coming to the Switch, too. By using streaming, it will be possible to play games on the Switch that its limited hardware otherwise wouldn't be able to cope with. Of course, making that work requires you have a reliable and high-speed internet connection. Hypothetically, this means that Xbox exclusive games, including the Halo franchise or Gears of War, could be played on the Switch with a Game Pass subscription using xCloud.
Microsoft has been expanding Project xCloud to a number of other devices including smartphones and it would be good for the company to expand its reach, especially with strong competition from Google's Project Stream, which will let you play PC games through the Chrome browser.
This would not be the first time that Nintendo has experimented with streaming games in this way. In Japan, Capcom's Resident Evil 7 is playable on the Switch through the cloud.
