Will we get Super Shredder in season 4 or season 5?

[neatoman]

Remember a while back when a Super Shredder toy was revealed? When do think that will happen, season 4 or season 5?

Most likely I would say the season 4 finale, considering that we have seen the toy already. Of course then there's the question of what will happen in season 5 if Shredder "dies", do we get a new Shredder like with the Demon Shredder or a new villain altogether? Or if it's in season 5 he mutates, what is the second half of season 4 going to about if it's not going to directly lead up to Shredder mutating?
