With the way Japanese TV schedules are set up this will mean the release date shall be sometime in September. I am glad it is not the usual ~2 year wait between seasons this time with how they ended the 3rd season and were so quick to announce this one.
I also like that there is plenty time for me to start saving up for the CD releases that are bound to come out with the series. I am curious how that will pan out since it looks like HEAVENS is going to play a bigger role in the series than they have before from how the 3rd season ended. I guess the closer to the release date the clearer that will get. Either way this is going to be an expensive fall for me.
