You have to make sure everything goes well when developing a game. Just because retaining some of the old ones doesn't mean less work. Don't forget the graphic engine had changed entirely for this game alone. Besides how about the upcoming units and buildings? And how about future expansion regarding this game? Perhaps starcraft 2 expansion is under progress too depending on the story line or campaign.

I believe the release is later than usual because of probably new staffs and perhaps maybe bllizzard want to make sure that this game will get screwed and they do have to compete with other strategy games. My bet, they are trying to be the best. Command and Conquer will be one of their worst enemies.

There's a possibility, all i can say. Don't make fun of the graphic though its not like CNC. Besides, not to mention when you're spamming units.

Seriously, is SC2 going to maintain to 200 units only?

There must be at least a speed upgrade for the night hawk
