I heard that NW is re-engining their 747-200s. As far as info about what NW Cargo will be after the merger, I have no idea. DAL Cargo perhaps? They've been downsizing recently, havent they?
You have to wonder how their (NWA) loads will look after Atlas/Polar starts flying the DHL freight in the Pacific. With Asia freight down 6% already it could be a huge hit.
