Maybe it's because they don't want to give us everything as soon as they finish it. They need time to bug test and make sure it all runs smoothly, and maybe the levels weren't actually coded in completely yet. Also, releasing it over time is a marketing technique to get more attention about new things. Think about it: When's the last time Angry Birds Classic added in an entire episode at once? Never. They always release it over time in two to three parts.
