WW2 probably not gonna happen. Because almost every major battle are allready been done in COD or other shooter.
So a single player will be hard. And cod is SP and MP.
And no tactics that's because of the players not the game.
And the next cod maybe a new serie also.
Timespan from something like the 70's to near future. Some bits from different wars.
In MP no fancy sight like tracer/tf.
More realistic and less rewards. Take the focus back to gun vs gun.
Map design: In ghosts they finally got away from the linair design. That's the way to go.
create a classe is now fine. Only the way to get members and points needs tweeks
operations more like the challenges.
CoD4 was in HD. Even though its probably the communities all time favorite, it would be absolutely ridiculous to revisit that game. As far as multi goes, I don't want to even see a reskin from MW let alone play the same campaign.
The Modern Warfare story is over, it only lives as a throw back on a dusty shelf and memories. I really enjoyed all 3 of those games, but I have absolutely no problem saying "see ya" to the series.
I wouldn't mind seeing the "old" titles revisited and made available to the nextgen consoles. But as for them being a full-on re-release, I don't know that I'd like it. I can see it happening, though. Movies and other games get remade, why not video games? That's speaking from an economics p.o.v., not a thumbs up or thumbs down p.o.v.
Amazingly enough, I have a feeling there will be a BO3. It would end the Black Ops series, though. It's too open-ended right now but there is actually a bigger reason I see a BO3 hitting shelves in November ... I think ATVI is going to want to end the debate over the direction of the franchise. If they bring back another COD that plays at the pace of BO2, the debate is over and all us fans of COD4 are history.
