So, for the uninformed, Pixar announced newt around the same time as Cars 2 and Brave. Cars 2 was moved to 2011 and then newt was moved to 2012. It was canceled in 2009. Pixar posted a bunch of artwork on Facebook a few years back and then yesterday, one former artist posted some on her blog but, took it down today. I luckily downloaded it all and put together a nice gallery of all of the released artwork:
