Actually, a more likely button might be "Sports" which would either open your preferred sports app (smarter way to do it) and default to Fox Sports, or a "Stream TV" type button that opens up Tubi which is already run by Fox, and surprisingly had decent content on it.
I'm not surprised they're going this route, and would not be surprised if News becomes a drastically smaller piece of Fox over the coming years.
Why would this be more likely? The current remotes already have a Netflix button, a Hulu button, a Sling button and a Disney+ button. Roku sells dedicated buttons on their remotes to the highest bidder.
