I think they said they would fix all the glitches that are blatant cheating. I don't think they consider the superjump as that, more of a "if you know how to do it" you can give yourself a nice sniper post kind of thing. Some little tricks are better left untouched. Besides, just about every h2 player can do that now anyway.
What have you noticed differently? Can't wait to get home and play!
