Let's just not get our hopes up too high with the box office, and let's not make unrealistic predictions, so that no one here can call it a flop when it doesn't meet our expectations.
There are 3 important things to consider:
1) It is unlikely this movie will appeal to anyone who hates musicals, no matter how much gore it has. People who hate musicals hate musicals. That's all there is to it. Blood will not change their minds... they can get blood in many other R-rated movies, without the music.
2) In general, it is very hard for an R-rated movie to break $100 million. Of the 23 movies to break $100 million so far in 2007, only 4 were R-rated.
3) Luckily, Sweeney Todd cost significantly less to make than both Dreamgirls and Hairspray... I think the budget was $50 million, which is at least $20-$25 million less than those two.
So, if the movie doesn't break $100 million but lands in the $70s or $80s, which I think likely, I don't think it should be seen as disappointing, considering it is an R-rated musical (and both of those things are often regarded as box-office poison).
