Blizzard Cancels StarCraft FPS, Reportedly Working on Diablo IV and Overwatch II

Years after Blizzard ghosted StarCraft: Ghost, Kotaku reports hearing from "sources," about another cancelled shooter in the StarCraft universe. They say "three people familiar with goings-on at the studio" inform them Blizzard has axed a first-person shooter codenamed "Ares" where the player would have been a Terran marine tasked with annihilating the Zerg. They say nobody will be fired as a result, since staff will be reallocated to a pair of unannounced games, Diablo IV and Overwatch II. They have an official response from the company, which sort of addresses the cancellation, but does not confirm the Diablo/Overwatch part of this report. They note they don't generally comment on such stories, except when they do:
We don’t generally comment on unannounced projects but we will say the following:

We always have people working on different ideas behind the scenes – including on multiple projects right now – but the reason we tend not to discuss them publicly is because anything can happen over the course of development. As has been the case at Blizzard numerous times in the past, there is always the possibility that we’ll make the decision to not move forward on a given project. Announcing something before we feel it’s ready stands the risk of creating a lot of frustration and disappointment, both for our players and us, not to mention distraction and added pressure for our development teams.

We pour our hearts and souls into this work, and as players ourselves, we know how exciting it can be to see and know with certainty that a new project is coming. Knowing that changes or disappointments can happen doesn’t make it any less painful when we have to shelve a project or when an announcement doesn’t go as planned. We always make decisions about these things, regardless of the ultimate outcome or how things might be interpreted, based on our values, what we believe makes sense for Blizzard, and what we hope our players will enjoy the most. The work that goes into these projects – whether they ship or not – is extraordinarily valuable. It often leads to great things and helps foster a culture of experimentation here.

With all that said, we’re very much looking forward to revealing other things we’re working on when the time is right.
