I'd say yeah - they'd be stupid not to. Activison has them signed to do a trilogy until 2019, with major expansion packs every year a new game in the series doesn't come out. So they're gonna have to get on next gen so I have no idea why they wouldn't now. However let's say it comes out in October but the PS4/720 comes out in Nov., it will come out then prob. Anyway, yeah I'm so stoked for this one.
I'm betting E3 they announce the new consoles but they won't be out till next christmas! They want to see if they can milk one more year.
Doing this on 360 makes sense. You need to build a franchise, so start the 1st game on the platform everybody has. Then the 2nd game will get everyone who doesn't already have a new console to get one. But this is activision, not Microsoft. This game must have been in development before the new console dev kits were available.
It's going to be on Xbox 360 and 720, with a PS3 version launching in Fall of 2014 according to court documents. There are supposed to be 4 games, every other year, with DLC coming out every other year.
I'd be very surprised to see it not come out on the Next XBox, provided Microsoft is indeed coming out with a new console. I'm sure Activision wants to milk as much money as they can with this franchise, so it'd make sense that they'd release it for all available core consoles.
Microsoft's Next XBox reveal is rumored to be this month, so we'll have to wait and see what happens. When they announce their console, that'll give developers and publishers permission to announce whatever games they have in store for it.
