When it comes to the new season being labeled as "Season 5" by some sources and even Dan or a cast member themselves, it is based on the production cycle. The production cycle number is connected with it's code number, and the filming cycle of this upcoming season is the show's fifth so the code number is 5xx. So this would technically be Season 5, but it is airing as Season 6. We know the Season 2 production episodes was split into two airing seasons and there's evidence to hint that was the case. But there are sources that happen to list it all as one season because of the production cycle, numbering the later seasons by their production number in the process (Season 4 as Season 3, Season 5 as Season 4, and now this upcoming season as Season 5) so this situation here means nothing. We must take into account that the 13 Season 4 episodes were even released on DVD as the "Complete 3rd Season". "Complete" meaning the whole airing season, and "3rd" in terms of it being produced out of the show's third season cycle (that's actually the real Season 3).

So as a result of the situation with the Season 2 production episodes, we know for a fact that what aired as Season 4 came from the Season 3 filming cycle and what aired as Season 5 came from the Season 4 cycle because the Season 4 cycle was split off from the intended Season 3 cycle where all 26 episodes were to be shot together. But we then had Dan saying the episodes "iLost My Mind" to "iToe Fat Cakes" were new season with the next number coding due to being a new filming cycle and not a continuation off the last one. Nick even advertised these as a new season in September 2011 but after "iLost My Mind" aired (due to "iDate Sam & Freddie" being the first produced episode of the season). And since the Season 3 filming cycle aired as Season 4, this was going to air as Season 5. So the next season that's produced as Season 5 will air as Season 6.
