So yeah, they fixed all those things mentioned in that post. I'm sad to say that Balrog still says "Oh Yeah" like some deranged kool-aid man. Typos and poor wording seems mostly fixed, although I actually only played from about halfway through (continued on a previous save).
Interestingly, they also updated a number of the facepics as well. As near as I could tell, the ones to get a revision were Curly, Balrog, Booster (who has a hideous underbite now >_>), Misery, Jenka, The Doctor, Itoh, maybe Ballos too. In fact, maybe they all got some kind of touch-up, but some were more noticable than others. I didn't really have a side-by-side comparison to go by.
Most of the regular sprites seemed same-ish, but one in particular I noticed is that the Night Spirits now have a decidedly creepier look, with circles for eyes (not solid circles), and :3 mouth. The Credits image with them has been updated to reflect this, and now there's two of them instead of one. Also they have whiskers.
