It'd be neat if they could do Germans, Italians, French, and British in Africa. But it'd have to be separated from the base game.
Won't sell in 'Murica.
You need 1943 Kesserine Pass up to Sicily and Italy with Patton (etc).
Mebbe they'll do a special 'Patton bitch slaps a PTSD sufferer and gets busted' DLC.
But seriously, North Africa would be great but without the Americans it's more niche than the Eastern Front (which is so huge it can carry itself marketing / interest-wise).
Plus, TBH, America 1943-44 on the African / Southern European front has some really interesting units.
Edit - basically call it Company of Heroes - The Big Red One and it'll fly.
