Idk know much about Reddit I joined the minuet I found out about this.
Its happening RIGHT NOW! reddit.com/r/IAmA/comments/3a3itv/i_am_dave_willis_cocreator_of_aqua_teen_hunger
Dave already responded to one of my questions!
If you read the Q&A he's giving out a lot of info, he even mentioned Dr. Weird and Steve will be back one more time in the finale.
He said its ending simply because [as] president Mike Lazzo is ready to move on from it. He mentioned maybe doing a Kickstarter to fund Death Fighter, but I'm still not holding my breath.
He even hinted that Carl's online spin-off might keep going after the main show ends
Sorry, Grapesoda, I'm out of town. Dang! I'm missing out.
Its too late he left. But there's a lot of good info if you read through the stuff he wrote.
I asked some questions under the fake screen name Jerry Stokes. 
and I was really hoping he'd respond to this but it was to late :(
What do you think?
