You're never going to get the Falklands, it wasn't large scale enough and didn't have enough major battles for a game, except maybe Goose Green or the advance on Stanley. It would be a developers dream come true though, nothing but green fields and slow rolling hills from horizon to horizon...
I don't know about CoD6, maybe some sort of fictional thing like CoD4 again. If they could do the SAS thing well again, then id welcome it.
