I agree with most of the opening post, with a couple things I'd like to add.
First, Wii Music isn't as accessible as Rock Band in terms of gameplay, but it's way more accessible in terms of price and peripherals. Gameplay is more important, but the peripheral requirement is a barrier that Wii Music doesn't suffer from.
Second, as everybody else has pointed out, it is way too early to call the game a sales failure. It's unreasonable to call a total below 10 million a flop just because this game carries the Wii brand. I think a performance of 5 million would be very impressive. I'm not convinced it will reach that, but it could surprise us all and go Brain Training on us.
In conclusion, this is a fun prediction you have, just don't pretend that it's already come to pass. :3
