You asked, loudly, and Ubisoft listened. Today at Gamescom, and on their official blog the publisher confirmed that Tom Clancy's The Division will be coming to the PC. From the blog:
Why PC… and why now? Much of the credit goes to the vocal and passionate PC community. “Since E3 we have been carefully listening to what has been said on the internet,” said Executive Producer Fredrik Rundqvist. “I can’t stress enough how important it has been for us to feel your support, interest and commitment to the game. Your opinions matter to us. The positive energy you bring back to the team will help us create the best game possible. One of the most frequently discussed topics has been that of releasing The Division on PC. With that in mind, I’m very pleased to announce that the game will be available on PC. Massive Entertainment has its roots in PC development with titles like Ground Control and World in Conflict. You can be certain that we will provide you with a first-rate PC experience.”
