Autodesk has released the full version of Smoke 2013 and you can download a free trial. It is $3495 per user license.
Damn, I wish I had played more with the earlier beta to get used to it, as I would really like to get proficient as the node based graphics tools (like the earlier Shake) are so powerful.
I still wish it was $1000, so it was more affordable to a normal user like me, but still it has dropped a great amount and looks to be a powerful editing and graphics tool.
