If you analyse the actions of Delta not the verbiage or rhetoric of Delta management and the former regime at DALPA, which it looks like you have done correctly, I would say you are correct. I was a 747 Captain at NWA for 12 years prior to merging into Delta and managed another 5 years in that capacity at Delta but now am a narrowbody Captain largely because of shrinkage of the fleet of large desirable widebodies. The management claim that "The A350 is the REPLACEMENT for the 747" doesn't wash since the first A350's don't arrive until the LAST and I mean last of the 747's are going away. When the begining of a new series of aircraft don't arrive until the last of it's predecessor are vanishing that is NOT a replacement, that is a business plan change.By the actions and deeds of Delta management it is foreseeable that Delta will evolve into a glorified Southwest Airlines with "gateway tentacles" of minimalist widebody flying into overseas gateway Joint Venture hubs. Lots of virtual airline stuff.
