Looks like Gearbox are teasing Borderlands 3

Gearbox Software are teasing something for their PAX East 2019 panel in Boston later this month, and all of the very large signs are pointing to a new Borderlands.
It all began with this. The cel-shaded style, desert, and bold graffiti are all highly reminiscent of the beloved shooter-looter franchise.

Here we have something a little more cryptic with a robot on an operating table. Perhaps the bigger Borderlands lore fans could squeeze out some clues, here.

Their most recent tweet, however, more or less confirms we’re getting a new Borderlands game.

But is it Borderlands 3?
After Battleborn dived, crashed and burned, gamers turned to the studio with renewed hope for a fourth Borderlands game. After all, that cliff-hanger in Borderlands 2 set-up some fascinating Vault possibilities, and the Pre-Sequel — as entertaining as the “space Australians” were — didn’t quite manage to fill fan appetites.
So either this is Borderlands 3 or Gearbox are prepared to deal with a tsunami of disappointment.
PAX East 2019 takes place on March 28.
