Possible? How?

As it looks right now (or at last year's E3), the Vitality Sensor does NOT have a port where you can connect the Nunchuk. Unless they are re-designing the Vitality Sensor, are we supposed to disconnect the Nunchuk, connect the Vitality Sensor and then stick something with a pulse in it, wait for it to check the pulse, disconnect the Vitality Sensor and then connect the Nunchuk again to continue playing? No thanks.

Zelda games don't scare me, am I doomed with "easy" difficulty then? I better start practising on how 'up my pulse to get the harder difficulty... OR they could just add an option at the start menu?!
