Last month Daybreak Games finally launched Planetside Arena, their new battle-royale take on the series, via Steam Early Access, which generated some excitement, but also some questions. Specifically, what was happening with the core Destiny-like Planetside games? Would we ever see a Planetside 3?

Well, in a new blog post, Planetside executive producer Andy Sites confirmed Planetside 3 is on the way, saying Arena is just a stepping stone to bigger, more ambitious things.
