Crunchyroll will have the first two episodes available tomorrow at 6 pm. PST/ 9 pm EST. They'll post 2 to 3 episodes every week after that until they catch up with what they have already streamed.

I am glad that I will be able to start watching this anime starting this weekend(since I don't like using fansubs) and have been wanting to watch more Key anime.
