When Microsoft vowed that it would resume releasing games on Steam, it wasn't making an idle promise. Microsoft and Remedy have announced that Quantum Break will reach Steam on September 14th for $40. You won't get anything special for your patience (just all the updates released since launch), but that's not the point -- the big deal is that you won't have to shop at the Windows Store to get a PC copy. If you were worried that Microsoft would use Windows Store exclusives as part of a bid to dictate the future of PC gaming, you can relax.
