It seems entirely un-impossible at this point that either 2K games or Gearbox Studios will not be announcing something Borderlands related come E3 in just a few weeks. With the Walmart leak a few weeks back pointing to Borderlands 3 announcement being forthcoming real soon, we seem to be getting extra hints that this could indeed be true.
The evidence for this points towards the fact that the Korean ratings board has gone and rated Borderlands: Game of the Year edition for Xbox One. Now if this what we highly expect it to be, I would say it is safe to assume that if and when this does get a release, it will be the first game bundled with all of the DLC that launched with the title all those years back. Seeing as bother Borderlands 2 and the Pre-Sequel have both been remastered and ported to the One, it will be a nice addition to get the first title added to the collection again too.
This will also be a nice lead into Borderlands 3 announcement we would fully expect too, just in case during the five years since the last game released, you have happened to forget what the series is or how to play it. When we hear more about this (most likely E3) we will be sure to let you know
