May I make a suggestion. If you plan on buying StarCraft 2, I would just wait until it comes out to begin this campaign. The models and editor would be much more friendly to the Alterway Storyline. Also, it is unlikely that a large campaign would be finished by the time SC2 comes out so you may have a better time just planning everything out in detail, storyline, maps, characters, etc., and then hitting the ground running once SC2 comes out. If you know you're getting the game, I would preorder it to get a beta key (are they still doing that?) and then fool around with the beta editor so you can get an idea of what it can do. Just a suggestion. I feel like WC3 will die once SC2 coms out, so it may be more beneficial to port over.
