That is HD, they can add aa, filters, etc. (that most emulators have).
They would need to do much more than just retouching graphics imo, or the remasters would get slaughtered in both reviews and general opinion.
Off the top of my head i think it would absolutely need trophies, time skip whenever you want, fast travel, detailed map (showing all points of interest), and possibly no loading times.
Edit: add no tank controls to that.
