The Borderlands franchise has now sold-in, i.e. shipped, nearly 25 million units. 2K Games parent publisher Take-Two Interactive announced the milestone as part of its latest earnings report.

Take-Two did not provide a game-by-game sales breakdown. However, the company said it shipped more than 8 million Borderlands games in its fiscal 2015.

Gearbox hasn't said whether the new Borderlands game is Borderlands 3, but given the fact that Pitchford has called it the "big one," it seems likely. No release date, or even a projection of a release date, has been announced for the game yet.
