Um, yeah, but the way they were describing the stuff they got planned didn't look like simple "cosmetic" changes to dialogues and so on. It seems that they're changing events, especially the way they are introduced so that the story flows better. I'm not tech-savvy, so maybe I'm wrong, but those kinds of alterations might imply save compatibility issues. At least, that's what happens every time they modify Summertime Saga's main story, although that game's saves have been a mess since the beginning.
