Another failure of a MS astroturfer...
Anyway, yes, it's very uncommon for people to transition from one console to another.
It's uncommon among core gamers already, and it's downright rare among casuals, like core gamers love to call them. It will be even more rare among Wii users. People that were afraid of the old controllers have virtually no chance at all to go to any of the other consoles. Their controls are just too poor and complicated compared to the Wii for that to happen.
Just look at PS1 and PS2. That's why what happens is that the good exclusive games migrate to the winner console.
Man, this makes me recall of when I was arguing with PC players back in the days. The guys did not understand that people playing Tomb Raider or other games with a joypad would never go play the same game with better graphics on the PC, but with a keyboard or a joystick. That just didn't make sense, but they believed it hard. Of course, it never happens. PC controls are so poor, that people (excuse-me, casuals) even prefer dual thumbstick rather than keyboard and mouse.
