That's what I am saying. However I'm not just basing it off my own opinion. Ninjago sets sold several hundred sets to one Hero. I saw several stores discounting their HF just to make room, but they are still there, taking space.
Though, it certainly looks like Lego is giving Chima a test run. If these six individual sets sell better in proportion to the entire 2013 wave of HF, then generally, I can assume production would be traded from the latter to the former. It's just their way of making money, much like how beautiful Ninjago was replaced with LoC.
