Those other three upcoming Xbox Game Pass titles are Flintlock: The Siege of Dawn, Dungeons Of Hinterberg and Kunitsu-Gami: Path of the Goddess, all of which are arriving day one on the service at launch!
It's also been teased that another update is coming soon, with rumours that Call of Duty: Modern Warfare 3 might be added to Xbox Game Pass in the near future. Here's that mention of "another update" from Microsoft:
"Let’s get to the games (and let’s stay in touch, we have another update for you soon)!"
Here's the list of titles coming to Xbox Game Pass from July 18-19
Along with these, it's been confirmed that three games will be leaving Xbox Game Pass in late July, with probably the most high-profile of the bunch being Train Sim World 4. All of these will be discounted until they leave the service.
It sounds like there's still some good stuff to come beyond July 19th on Xbox Game Pass this month, so let's hope that next update isn't far off at all. Could we be playing Modern Warfare 3 in just around a week's time...?
