Completely invalid arguement. Whether the Nunchuk is seperate from the Wiimote or not, the fact is, they could require you to attatch it to play the game like on Zelda or Red Steel, in which case there would be a control stick to tilt. I'm just saying, this doesn't prove that they won't be using the wiimote to play the game, though I'm totally with you on the fact that motion controls/using the wiimote would totally suck.
Even so, this is only in one aspect of the game. Who's said anything about it not being in any other part?
