iLife is too important for the marketing to stock away inside the OS release. They cannot fill those shelves in the Apple stores with only third-party consumer software. My guess is that they will indeed hold a seperate event in a couple of weeks (they will probably allow some time for the Vista buzz to die off) to present some new stuff including iLife & iWork. They know darn well that no journalist is going to write about iLife or iWork if an iPhone is presented at a keynote.
