I could see them keeping the initial waves small to permit fixing any critical server issues found before too many are in. I understand the logic of their plan and a few days wait has zero impact on me. But humans are not always logical (read any history book for details) and people are really excited about getting into the game. Given the pull of the game is emotion (ie, the story), they miss that aspect of their consumers. Just wish people wouldn't be so nasty... (see reference to any history book, not a new thing).
