No, the "purist edition" is just Revisited without added music, and with the scene in Obi-Wan's hut restored to its theatrical cut. (I think one or two other things may be different.) But other than that, it's Revisited, just ... less revisited.
And Ady, that is bloody fantastic news! I know it's early, but do you think you'll be using the 1977 crawl, or the 1981 crawl?
