Disclaimer: This is for games newly released between 22.05.2015 and 28.06.2015. I'm only including games that have more than 10k owners, there's a lot of great games that sold less than that, but I don't think Steamspy results for such low values are statistically sound. I did remove the games that left Early Access this month, as they had a lot more time to accrue owners (Tabletop Simulator, Audiosurf 2, Massive Chalice)
Also, standard Steamspy disclaimer applies - those are ownership data, not revenue and definitely not profit. Many of these games have been discounted during the Steam Sale, a few have been bundled already/before release.
With that in mind, here's the top 10. Full results are available
