For those who missed the ongoing discussion, it is official. Galileo will be the fourth Eclipse simultaneous release following Callisto, Europa, and Ganymede.
Io was due up to be the name of the release as the fourth of the Galilean moons, but given that "Io" looks a lot like "10" and "I/O", the planning council went with the name of the astronomer who discovered these four moons. An excellent choice.
Cheers to Galileo.
