For PC and PS4, I don't see how they could have just throw away the HD textures after the conversion.
At the very least, I think they should re-release the HD textures in increments if they don't have the manpower and resource to do it all at once. Start with HD character models so people can stop making threads about flatbutts. Then move onto gears, then monsters, then background environment. It's not a lot to ask but will please fans for years to come.
