Is Wii Music gonna be the next Guitar Hero? I mean super popular?

I was under the impression from the presentation that you were still required to use timing. Nevertheless, I'm not sure about what to think on this one. Admittedly, if looks a lot more forgiving than either Rock Band or Guitar Hero, and for a lot of people that's a good thing. The sheer number of musical instruments is also a sizable plus. I think it will sell reasonably well, I'd like to hear more hands on before I get more specific.
