Best answer: We don’t know for sure, but there’s a strong possibility that Borderlands 3 will come to Steam after its 6-month exclusivity period on the Epic Games Store.

Why is it an Epic Games Store exclusive?
There are a lot of reasons that could have contributed to Gearbox and 2K opting to release Borderlands 3 on the Epic Games Store as a timed exclusive, but the companies have unfortunately not stated why they came to this decision. A popular belief is that it is because Epic only takes a 12% cut of the revenue as opposed to Valve’s 30% cut, but that is merely speculation.
When will it come to Steam?
According to a press release released after its announcement, Borderlands 3 will release on other digital PC platforms starting in April 2020, six months after its initial release on the Epic Games Store. However, because it doesn’t specifically list Steam as one of these storefronts, we can’t know for sure if it’ll come to the popular PC platform. As of right now, it’s an educated guess that Steam — being the biggest digital distribution platform of video games — will likely get Borderlands 3 in April 2020.
