Wii Sports was (and is) bundled with every Wii outside of Japan. Calling it the best selling game is a bit of a stretch considering in most of the world you can't buy a Wii without it.
I don't think MW2 for 360 will outsell Halo 3. I'm not a big Halo fan, but that game has consistently been in the top 3 most played games on Live since it was released. MW2 may get reasonably close, but I don't think it will ever dethrone it.
