Yes, the retired videos are the main reason.

By the way now that you are caught up to full, you can use Peter's website to keep track of new videos (or the KA API). This will allow you to catch new videos before they fall through the cracks. Personally I am always interested in seeing the new material that pops up and trying to use it predict where KA will go in the future!
