Activision announced earlier this year that it would be the exclusive publisher for the next original game from Halo creator Bungie, both parties would not confirm which game platforms the title would appear on. Today, during an investment conference, a slide may have revealed that Bungie's next game series will indeed show up for the PC.
The online slide was part of Activision's presentation today during the BMO Capital Markets 18th Annual Digital Entertainment Conference. As you can see above the listing is for Bungie's new title to be for "Con" (consoles) as well as PC and online. If this is indeed the case it would be the first internally developed PC title from Bungie since Oni was released way back in January 2001 (Both the PC ports of Halo 1 and 2 were handled by developers outside of Bungie).
