hhn was not all that scarry... the best one(in my opinion) has to be the one that the care taker was at... that house with maximum carnage was done really well...

as for new rides and attractions...
they took out king kong to put in the revenge of the mummy ride, an indor thrill ride/ roller coaster(no loops, just drops and sharp turns...)
the have now closed the wild wild west stunt show for the new up-comming walk through/ride fortress dracula. there, they will be a small stunt show, a gallary of things from the movie, how they did the make-up and characters from the movie you can take pictures with....(frankenstine, dracula, the wolf man and van hellsing himself)
as for ioa... every thing is the same....
word is.. they might be changing dr. dooms fear fall to a real drop and not something that shoots you up...( you will go up slowly and then drop)
i hope this helps you alittle bit...
