Lets just say that the odds of Halo 3 failing FINANCIALLY are so small its not even worth it to talk about em. Now on the other hand Halo 3 could fail as a game on the whole for several reasons. The MP is horrible. Halo fans hate the storyline. Online experience isn't good. However this is Microsoft and this is Microsoft's prize possession IMO so they're not gonna f*ck it up. That would be like Nintendo putting out a SSBB which is complete sh*t. We'd all revolt and Nintendo would be in deep trouble. So no I don't think Halo 3 will be a failure.
