As for Dominions 3:
Anybody, who is interested in the game, is welcome to the forum. It contains mostly, as you can see, speculation and some answers too about the content of Dom 3. Some people try to suggest some new features, but I think mostly in vain.
Release date is supposed to be in this month, but although Illwinter working hard, it seems that the game will be delayed. Maybe in August. Please.
Oh. You might also want to check out the progress diary of Dom 3 in the page one of the thread "Dominions 3 development news" in the Dom 3 forum.
