Suguha is totally the main character now. Every scene with Kirito also has her, there are plenty of scenes with her and not Kirito, and all the thoughts we hear are hers. I definitely wasn't expecting that, since for the first half of the series it seemed like Kirito's little "sister" would never have much importance. Plus, some fanservice with her that's more than this series has really done until now.
