Pluto's flyby generated about 8GB of data and it took about 16 months to get all of it downloaded [1], and this data includes more than just the images, and i read somewhere that the Ultima Thule flyby will generate about 6GB of data.

I think the images are the first thing that get downloaded, so it should not take more than a week to get all high res images.
