nothing seems really strange for me at this point. Though I tend to see day one as mostly a fluff day. Thus one little different. Joke and flavor posts with most of the usual things that follow.
Considering the game ends day 5 unless the perp is caught. It seems very likely there will be more than just town and mafia. Though I already said as much in the post you quoted. To expand upon it though I do that there is a faction out there that wins on day 5 if not stopped and I could see it as one person so that even mafia will be trying to find him.
