All the recent talk about TNG remastered really made me ache for DS9 to be remastered. I think TNG is shoe-in for remastering, it's only a matter of time. I think DS9 is less safe a bet. But there are definitely things that can benefit from it. E.g. I would change the Melbourne back to a Nebula-class starship, for one. I would put more different ships at Wolf 359 (e.g. Akira-class). I'd tone down the use of Mirandas and Excelsiors in the big battle scenes. I'd definitely give the second Defiant it's proper registry (NCC-75633) (unfortunately, they kept Constellation as NCC-1017 which is as glaring an error as imaginable so I'm not too optimistic. in my mind Constellation will always be 1710).
