I see it more simply than that:
The initial Wii Remote was designed to capture the imagination of non-gamers who want to play videogames...but I think Nintendo probably knew internally that it wasn't good enough in terms of control for traditional gamers long term.
So the Wii Remote was for non-gamers.
But the 1:1 accessory had unbelievable applications for the so called "epic games" that we hear so much about from people who think Nintendo has gone bat shit insane in ignoring its audience. Swordfights. Great FPS Controls. Great Boxing Games (new Punch Out?). Wave Race/1080? All these things for core gamers are possible with 1:1 control that weren't with the limitations of the Wii remote.
Can't say I expected to see 1:1 this generation (I was thinking Wii 2) but it does make sense and I think its the secret to the ongoing success of Wii, as Iwata as early as E3 2004 sounded like he knew Nintendo's current innovations would eventually become standard fare and copied.
