Isn't Nintendoland mostly a multiplayer affair? I'm just pulling this out of the air, but:
$249 - White - System and tablet controller
$299 - White - System, tablet controller, wiimote+nunchuk, Nintendoland
$349 - Black - System, tablet controller, wiimote+nunchuk, Nintendoland, pro controller
$49 - Nintendoland + wiimote and nunchuck bundle
Since you need wiimotes for the multiplayer in Nintendoland they will bundle it with an extra wiimotes in an attempt to replicate the incredible success that Wii Play had. The problem is that we are probably already saturated in extra wiimotes so who's going to need them?
