The featurette also has a priceless mini-movie that they made called "The Evil Dead Baby," which looks like they just made it durring downtime with a camcorder.
Honestly, I think if they did release another special ediiton, I'd imagine it would just have more new retrospective interviews and stuff, but all the archival footage would pretty much be the same stuff that's on here.
This DVD was also released as a limited edition Tin, which came with a mini (just bigger than postcard) movie poster, and a neat booklet, but the content on the DVD itself is exactly the same. I know this from experiance because I bought the non-tin version and sold the tin on ebay because I hate DVDs that don't fit on my shelf properly.
