Avatar the last airbender: Zutara?

[sweetrapture]

I was wondering if it was true that the writers of Avatar the Last Airbender did intend for Zuko and Katara to get together, but went with Aang and Katara because it was better for the kid viewers.
If you guys know that this is true, could you possibly link the interview in which they say this ?
I'm just curious =]
thanks!
