Well Jett8 and Great wall are no longer.
FedEx now base a B757, but, would be great to have the MD11 to MEM back.
Air China and China Airlines. Not sure why they left but it would be great to have them back.
I guess the latter 2 and Cathay are just a by-product of the downturn. Hopefully one day they will be back, but, no point flying round empty freighters if the demand is not there. I hear most of the products the B744's used to ship are now sent by sea.
I suppose we will have to make do with the Lufthansa MD11, FedEx B757/ATR base and Cathay, along with the ad-hoc stuff like Saudi (not sure what their B744 took away from MAN) and China Southern (if they need more pigs) every now and then.
