The Epic v. Apple trial is revealing far more than Apple's rules against iOS apps and questions about what people are willing to do to get Fortnite Mobile back. For example, confidential emails included as exhibits in the trial support rumors in 2019 that Walmart was, and perhaps still is, working on its own cloud gaming service. [Ed, Matt and I met with Walmart executives to hear their blind pitch (we didn't know they'd pitch a streaming service) and it was intriguing." Epic Games co-founder Mark Rein wrote in his 2019 email chain.

"I played the Walmart demo on my Android phone (using an Xbox controller) and it felt like playing on PS4, better than playing on Android or iOS. I also transferred it to my laptop in real time (the video stream instantly hops from my phone to my laptop) and played it there as well. Again, my daughter's Surface Pro laptop (the most expensive version!) ) and was far superior to playing on the crappy business laptop they brought with them.

Rein also seems to suggest that Walmart's system is better than Google Stadia, writing that Walmart and Nvidia's GeForce Now service (which Epic also noted) runs on Windows and directly It notes that it supports. Google is a complete port to new operating systems and platforms with its own APIs, etc."

The document includes elements of Walmart's presentation, touching on how the company is "positioned to win at digital gaming" and how the service is being built and what it could become:

The current status of Walmart's streaming game service is unknown, but according to The Verge, the rollout has been put on hold due to the Covid-19 outbreak. However, in a reply further down the email chain, Epic's Arjan Brussee clarified that Walmart is already past the fact-checking stage. 'They are running Fortnite (PC version) on the Edge cloud and streaming it to all platforms. They plan to develop and deploy this very aggressively."

I have contacted Walmart for more information and will update if I hear back.
