Randy Pitchford wasn't the only person to tease Borderlands 4 - that honor also goes to a Borderlands 3 and Tiny Tina's Wonderlands writer who hinted at the reveal trailer two years ago.
The Borderlands 4 reveal trailer shows, among other things, a heavenly body appearing in an alien sky, smashing through some kind of barrier as it goes. Eagle-eyed fans think that planet is actually a moon, Elpis, on which the events of Borderlands: The Pre-Sequel took place. That, in turn, has turned up some pretty gnarly Borderlands 4 fan theories (only some of which have been squashed by Randy Pitchford).
