I hate buying a DVD and having a "better" version released only weeks later.  That really pisses me off....see T2, Evil Dead, Robocop, ect.......
I know what you mean.  They come out with a unrated or special version with a few more goodies.
I hate special editions that aren't special.
The ones that only have the preview in the extra's menu.  I at least want some deleted scenes, or interviews
