Well, if they could capture the same scary qualities of the original but do so with a little bit more money and make-up technology, I'd be all for it.
The original is well done in many ways... but suffers in the SFX department. It could have also stood to give the characters and their relationships a little time to develope.
However, I don't like CGI in horror movies. A little well placed and subtle CGI is okay... but when it all becomes CGI, it takes me out of the moment. It turns a horror movie into the Star Wars Prequels. I prefer a lot more practicle effects in my horror movies. It can be enhanced with a little CGI, but that's it form me. I never even went to see Drag Me to Hell, because all I saw in the trailers was a bunch of obvious CGI.
Keep it dark, keep a lot unseen and mysterious. Keep the dark comedy, but don't turn it into the shtick that AoD became.
To me the first one was great, the second one got a little more comedic, but was still scary and gave us a bit more time with the characters and a little better make-up, the third was just a comedy. There was nothing scary about it. All of the added effects were lame. It was just a bunch of corny one liners that robs the first two... it's the Batman and Robin of Evil Dead.
