Let's speculate as to what the deal breaker was with a list
 

Here are my random speculations of what the deal breaker could be. I don't think all of these are possible at the same time, but perhaps some may be similar to what they do. My speculation:

1. The Turtles now list in the outskirts of the city in the "Shell of Justice" instead of the sewers. It is shaped like a giant Turtle dome.

2. Images of "Bam" "Wham" and "Pow" now appear on screen when the turtles get into fights.

3. The turtles use Don's holographic disguises to walk around the streets in human form. Mike looks like his human form from the OT "The gangs all here."

4. April is now a High school student who must keep her discovery of the turtles a secret from her parents. Her bedtime is also 10pm.

5. Baxter Stockman is now the sinister science teacher at April's school.

6. The turtles have human crushes, but they can't let them know they are really mutants under the holograms.

7. One of the turtles has become the "scaredy turtle" who is afraid to join battle with his brothers.

8. Shredder and Splinter are now brothers who wage war against each other.

9. Splinter's whiskers now sense danger ala Spiderman's spider senses. His whiskers also point in the direction of danger.

10. Casey is now a mild mannered mailman who only goes beserk when he wears his hockey mask ala Two-face.

11. Mike has a pizza business in the world where we see the return of Cowabunga Carl.

12. The turtles all do a boogie dance after they win every battle.

13. The turtles all have a direct phone line to the police where they can jump into the action before the boys in blue.

So what could the deal breaker be? Any ideas?

I have no idea, and I really don't care about it. All things will be revealed in time. You just have to be patient.

Wow, this was a short-lived speculation because lookie lookie - 'twas a teenage April that left a bad taste in the group's mouth.

For JoeGro, the issue was a tall and "young" Splinter who would appear to be Shredder's physical match. If I recall, JoeGro was the only invite who claimed the term "deal-breaker."

Anyhoo, maybe it's time to lock this thread and close up shop?

Well for most of us it was Teenage April and the very open crush Donatello has on her.
Please remember though that the show is in it's very early stages and anything can change.

That was the deal breaker? God I hope they don't listen to any of you guys, I love the idea of teenage April and I'm ok with a turtle having an open crush on her. This is why you don't only take NERDS to events like this. Now I like you all but seriously, that was the deal breaker? wow way to overreact. I LOVE the idea of teenage April.

*I realize by deal breaker you guys don't actually mean deal breaker but one thing you all decided it was a terrible idea

There was no point to her being in the show.
There's also more to it than that because it seems like they are teen happy with the cast.
They did have more there than just NERDS btw.
It was more the fact for me anyway that the turtles lose their motherly figure, she's a boring empty typical teenage girl who is just there, not to mention the Donatello thing.
When she is around everything gets all off track and the turtles make fun of Donatello for nerding out over her.

because everyone that where at the event are nerd-raging?

It was not a deal breaker for all of us (not for me), but everyone felt thumbs down on the idea. And it wasn't just that she's a teenager. It was also her design and her undefined role in the show. Everything we saw led us to believe she was simply a kidnapping victim. Everyone in my discussion group was open to this new April if she could be designed to look a little older (because she didn't look 16) and actually be someone important to the story.

And I think Nickelodeon picked a fantastic group of people to attend that represented a wide range of fans. But thanks for insulting all of us anyways.

Oh btw the NERDS thing was tongue in cheek and not an insult, I mean I'm a huge geek. I forgot to add winky here ;) in the post and I didn't re-read it so I didn't see if it came off as hostile :p

Good idea, there's no point in speculating about this anymore.
