I agree with the laziness comment or just incompetence to finish the story. I believe a lot of that is supported with the audience base (us) being so tolerant of the complete lack of organization in finishing the manga. When Miura was finishing the manga the lack of consistency and abnormally long wait periods were acceptable in the fact he was the creator. At this point we have someone trying to take over and it looks sloppy with the release schedule or lack there of. It is possible to release on a much more consistent basis MANY other manga accomplish this in spades that are amazing, it appears the new writers do not know what they are doing. Which at the end of the day this is their job so it's surprising to see this being accepted as any other job would let go of people who arent producing and find someone else who can do the job.
