During a recent interview with Comicbook.com, Brian Teen explained that he doesn't think we've seen the last of Shredder at all. He believes that the villain will most certainly find himself unfrozen at some point -- following his betrayal at the hands of Krang -- and when he's finally thawed out, he is going to be incredibly pissed off. Shredder isn't the type of guy you want to enrage, so it sounds like a war with Krang may be on the horizon. Perhaps he will even team up with the Turtles in order to make that war a reality.
