From the Star Wars: Revisited -The Saga Facebook page:

Well it's 2013. I hope everyone had a great Christmas and New Year.

So now it's the year we will see ESB:R finished, there is a strong possibility that i will be doing a few ESB:R Behind the scenes video blogs starting Late Feb/ early March. You'll get to see how some of the miniatures sets and models are made along with some of how the FX shots were created.

The final blog, a few days before ESB:R is released, will give you your first glimpse at the new Wampa.
