From the press release: "Freeverse announced today Heroes of Might and Magic® V for the Macintosh, under exclusive worldwide license from Ubisoft is shipping. Developed for the PC by Nival Interactive, Heroes of Might and Magic V brings the popular and long running strategy franchise into a new era with cutting-edge technology and a breathtaking, fully 3D animated world."

Freeverse finished the game a while ago (late January) and was waiting for Ubisoft's final approval -- there was no official gold announcement. Another good news is that PC-to-Mac networked LAN games work, which is a first in the history of the series as far as I know.
