Borderlands 3 is getting a free PS5 and Xbox Series X upgrade -- and four-player splitscreen - The Verge (https://www.theverge.com/2020/9/12/21434185/borderlands-3-ps5-xbox-series-x-next-gen-upgrade-4k-60-splitscreen)
Gearbox isn't making the same promise to would-be owners of the cheaper $300 Xbox Series S (https://www.theverge.com/2020/9/10/21430298/microsoft-xbox-series-s-hands-on-photos-price), of course, since that console that's generally targeting 1440p resolutions instead of 4K.
lulz
I wish all shooters would have split screen online.
