this is old news. Bungie signed with them months ago. The only new story today is that they took out an advert looking for someone with ps3 experience. But it was already known that their next project will be a multiplatform release.
From what i recall, bungie signed a pretty reasonable deal with activision. Similar to ea partners, bungie will keep all the rights to their ip (which obviously will not be halo as microsoft owns the rights to that). Activision does not own bungie and will not be able to do to them what they did with infinity ward, nor will they be able to whore out bungie's games the way they've done with guitar hero and cod. All activision has is publishing rights. Don't jump the shark.
