Tension is mounting: in a press release, the Blender Institute has announced that Sintel will be released on line next week Thursday, September 30th. The official movie poster has also been released. Pablo Vazquez shows the production steps on the Durian blog.
I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.
