Celestial Heavens got a confirmation straight from Rob King: the sound producer and his long-time partner will be working on Ubisoft's Heroes of Might and Magic V:

"Paul Romero and myself will be scoring the soundtrack for Heroes 5. It is going very well and we are really excited to be working on the franchise again. It has been over 10 years now working on the Heroes of Might & Magic Games and we still enjoy it tremendously. We have a couple pieces finished and are starting to work on a couple "Town Theme" orchestrations. All I can say is the soundtrack is going to be very emotional and a cut above the previous scores!"

Thanks to Rob for getting back to us as soon as he could. We hope our spy at the E3 will be able to listen to a track by the King of Heroes.
