Not surprising to anyone in planetary science. The chemistry always made it a certainty. The question was always about what phase the water would be in (solid ices, liquid, etc.).
Basically, you can’t have a planet with that deep of a gravity well, surrounded in space by icy bodies… And not have had it capture a bunch of it during formation.
