Regarding the "fifth season"
The news article that was linked to the wiki article relating to the supposed fifth season mention YTV purchasing more episodes, but I can't find any mention of that. The only thing that lines up is Corus' press release saying that new episodes of Evolutions will be released in the Fall, but since the current season ends in September I'm not sure they're talking about anything new.
