A new Borderlands game has been expected for some time now. The series is among 2K's most successful franchises, and Borderlands 3 has been teased time and again. We know 2K has a new (but as-of-yet unannounced) game for one of its big franchises in the works, although it was recently delayed--rather than releasing by the end of March 2019, it's not due until sometime between April 2019 and March 2020. That suddenly makes it less likely that E3 2018 is where we get a look at Borderlands 3--or whatever the game ends up being called. Nevertheless, here's what we know about the potential project, as well as what we'd hope to see from an E3 reveal.
