User blog comment:DevonAndersen/Season Number Change Poll/@comment-3123404-20120221225051

I'm sorry, but the episodes from the 2010-2011 season and the 2011-2012 season are two different airing seasons. The production filming of 26 episodes for Season 4 were split so the second half became it's own production season hence why the number coding was different. So it was going to air as a new season. Different number coding mean a different season. We have Miranda saying on her twitter account that the new season was Season 6 due to how it's going to air. It's labeled Season 5 in some sources in terms of production because of the 5xx coding.
