Update: Looks like this was a “joke” by Bungie. Coulda fooled me.
From IGN:
At a panel session at the Game Developers Conference in San Francisco today, Bungie lead network engineer David Aldridge confirmed to attendees that the developer’s next title is a “massively multiplayer action game.”
Rumors about the game have bounced around the internet in recent weeks, with anonymous sources describing the new project as “WoW in space.” At his talk, titled “I Shot You First: Networking the Gameplay of Halo: Reach,” Aldridge specifically noted that the title is not “WoW in space.” So there you have it.
I never liked Planetside because the action felt really fake and sluggish. Bungie has made some of the tightest controlling shooters ever. Put them in charge of a Massively Multiplayer action title and you suddenly have a shot at making the first MMO shooter that has a shot at being as great as World of Warcraft.
