looks pretty cool, don't know if you noticed but on the same site they mentioned that their bringing back classics from the 90's like Kennan and Kel, so i got two doses of good news

Why does Donatello have a naganata, I thought he was a pacifist? I really like the newer cartoon but still as big ninja turtles fan I'll be watching regardless if it sucks or doesn't suck.

wait wtf....how the hell do you change Donatello and Michelangelo's weapons??????   NO!

I never seen a nunchuck with a blade on it before.
Looks LAME.

They've not changed the weapons. The turtles will all have their signiture weapons but apparently they will also have a  secondary weapon. It's not unheard of for the turtles to use other weapons since they're supposed to be trained in multiple weapons.   And while Don and Mike may be the least violent and likely to kill but they're still willing to.

this version of the franchise will be “funnier and ninja-ier,” and from the look of fierce concentration on these turtles’ faces, they seem a little tougher than previous incarnations

Nickelodeon sent us the video as well. So now it can be seen on our spiffy video player.
