I couldn't agree more. JSA was one of my favourite books and I can't wait for the new series(why they had to stop it is beyond me!!).
I never did see a stated reason for that, but I don't search for comic news all that much. If you ever come across one, let me know, because it didn't make sense to me either. And the way the series ended didn't really give a satisfying storyline reason either.

I just assumed that Johns got overloaded.
