Yeah he have at least five episodes coming in 2009 and that's it, unless a new season is ordered.
Not a bad episode but well come on two episodes left, and only like a third of the characters we saw BTTS designs for have shown up yet. Does this mean in the final two episodes we will be getting Karai, the Justice Force, Mikey as Turtle Titan, Leatherhead, and Usagi and Gen in at the same basic time? Sure most of them will probably show up just for the weding that was already spoiled but still thats a lot of characters and we only have two episodes.
Anyway Every Turtles (But Ralf) has beaten Shredder in a 1on1 battle over the course of this show (Meaning 2k3 to now) Even if Mikey's victory was pretty much identical to how Splinter beat Shredder in "The Shredder Strikes"
