It definitely gives the impression that he's lost interest in this game because he doesn't want to remake the whole game in the current art style (not sure how much is left for him to upgrade) and is bored of the direction it was heading so he'd rather make something new to get that honeymoon feeling back about a project.
I would much prefer he get this game to a 1.0 before moving on. It would also give me much more confidence in paying for this game and any future ones he plans to make.
