Will Halo 5: Forge eventually come to steam?

I’ve noticed that Quantum Break just released on Steam (Which was a Xbox/Windows 10 exclusive but now can apparently work with Windows 7). So that makes me wonder; Will Halo 5: Forge be coming to Steam as well? If it were to come to Steam, do you think the game would become much more popular? Would you play it (if it supported Windows 7 as well)? Let me know what you guys think.
