I doubt that Ichigo is done with his training in the Royal Realm. I don't think that he is as strong yet as his peak, but I think with additional training he will quickly get stronger. It only makes sense that Ichigo+fake zanpakuto+hollow powers hollow training --> a lot more fighting --> dangai training --> fight with Aizen. I wouldn't be surprised if the new arc follows a similar pattern.
