According to a report from outlet Direct Feed Games, an outlet that has a strong track record for rumors especially centering around Nintendo, Microsoft and Nintendo are about to get together in a big way in the near future. Not only will some Microsoft games find their way to the Switch, but it looks like the entire Game Pass library might arrive via the magic of streaming.
The report states that Microsoft is looking into publishing some of their own catalog to the Switch in the form of actual ports. This is in no way strange for Microsoft, who has dabbled in things like lending out Rare for games on Nintendo systems and developing and publishing games on Nintendo consoles such as Minecraft. Microsoft-owned developers like Ninja Theory and Obsidian are still self-publishing their games on the Switch and other systems, as well.
The game specifically mentioned by Direct Feed is Ori and the Blind Forest, a crown jewel in Microsoft's lower key publishing initiatives.
Additionally, the report goes on to say that Microsoft will be leveraging their announced Project xCloud streaming service to bring Xbox One games to the Switch. While the Switch can't natively play, as a hypothetical example Gears 5, it could stream it over the internet. This will be done through Game Pass, which allows players to subscribe to a service to access a Netflix-style library of games.
In talking with our own sources, it has been suggested that the announcement of Game Pass on Switch could come as soon as this year.
