The Russian gaming magazine FIM (For Imp Magazine) included much more than a cover picture of a girl trying to extract herself from the mouth of a bear (how kinky!). The Archangel Castle forums contains descriptions, in English and French, of the Orcish town creatures and the alternate upgrades, including a peak at the line-ups that have yet to be revealed by Ubisoft. Here are some excerpts:

• "Cyclops is a strong hand-to-hand fighter, with an ability to attack walls, when in siege battle. One of the upgrades for Cyclops can shoot beam from his eye that affects several creatures, and decreases his victims luck."
  
• "High Druids can perform special ritual, which transfers their magical power to hero, adding him spell power. The effect lasts until there are no more druids alive."
  
• "Harpooners can shoot harpoon that in addition to standard damage can pull the attacked creature by one tile closer to the harpooner."

It is also said that the hero superabilities (the ultimate skills I guess) will become more accessible, and that both standard and alternate upgrades will cost the same. You can read the whole thing here.
