No, it won't, as I am already back to playing my Madden 10 franchise over BB in the limited time I have for any games during the week. I am already playing Madden 10 again more often than BB. I played Madden 06 until 07 came out.
I'll probably have gotten more out of Blitz: The League than I will out of Backbreaker, and I stopped playing that altogether after a couple of weekends.
I play football games for a good game of real football, not for pretty tackles. BB is nice to look at, but it's an arcade football game for the most part and as a result will have very limited appeal to people who like realistic traditional football games.
