Gearbox Reveal at PAX East, Possibly ‘Borderlands 3’ ?!?!?

It would appear that developers Gearbox Studios are set to unveil their new game imminently. On their Twitter, a teaser image with a highway sign for Boston, Mass. points towards a PAX East reveal.

The interesting part is the cutoff “3” at the top right, leading many to believe it is a Borderlands 3 tease.
March 28 also happens to be the day Gearbox is holding their panel at PAX East’s biggest hall. It promises “never-before-seen reveals, exclusives, and surprises.” The event will also be streamed live for global audiences.
