No offense, but the reason I am pro-"I hope they replace ships” is because the VFX personnel at the time were hamstrung as to what they could use. There was no artistic integrity involved there. If they had the time and budget back then to make new ships and not have to rely on stock footage, believe me, they would have. Now, they would have that time. Of course, there will probably be an entirely different crew working on the VFX for the remaster, so they'll still probably just do it in the quickest and cheapest way possible, which is to either upscale the existing footage or make new FX by mimicking what was there before.
