We've asked Bethesda if the releases will be exclusive to Steam. It didn't mention as much in the announcement, but we wouldn't expect these titles to come to the Epic Games Store (or other portals) regardless.

The developer isn't necessarily taking sides in the battle between Steam and Epic's store. Still, it's hard to shake the comparisons -- Bethesda is making its move right as a slew of big releases have been announced as EGS exclusives. Like it or not, you might have to run at least two launchers to cover the bulk of major new releases in the future.
