Linux / SteamOS support?

Rock of Ages was one of my favourite games when it came out. It also made me love the ACE team.But then, none of the games made by the ACE team have been released for GNU/Linux. :(Will there be a Linux build of Rock of Ages 2 this time?It's made in Unreal Engine 4 this time, right? It should at least support Debian / Ubuntu.Please make me love the ACE team again!
