This is kinda old but I just wanted to share something. Apparently, Jason Biggs is leaving the Nick TMNT show. I don't know why, but he left. We've gotten hints that he was going to leave before due to his voice not being in the last few episodes of the season. Now, it's confirmed that Seth Green of a Robot Chicken fame will voice the leader of the four turtles. Honestly, I'm ok with it. I'll be a bit sad to see him go as I did like his voice for Leo. Hopefully Seth does Leonardo justice.
