Tim Sweeney spoke at something called the “Global Conference for Mobile Application Ecosystem Fairness”. According to MacRumors, here’s what he said:

What the world really needs now is a single store that works with all platforms. Right now software ownership is fragmented between the iOS App Store, the Android Google Play marketplace, different stores on Xbox, PlayStation, and Nintendo Switch, and then Microsoft Store and the Mac App Store.

Sweeney isn’t just talking about Apple and Google there, he’s talking about all console makers. My bet all along has been that Tim Sweeney wants the Epic Games Store to become the Amazon of software, and that ambition necessarily goes beyond Android and iOS.
