One of the main problems Linux is facing as a gaming platform is the absence of support from any major publisher, but that is about to change. It seems that we might get a Linux version of Watch Dogs on Linux.
Ubisoft is certainly one of the biggest publishers out there. The company is responsible for a number of very important franchises and it does most of the work in-house, be it some Tom Clancy game or the next Assassin's Creed.
To be fair, there already are some publishers that have shown their support for the game, and 2K is probably the biggest one of them. The newly-announced Civilization Beyond Earth will be arriving on Linux, although the port is being handled Aspyr Media, which is not exactly ideal.
