I (almost) can't believe it...
The CN site has info on the Wii U systems and their coin values.
Both the Basic and Deluxe Wii U sets are worth 160 coins.
That's pathetic.
What's even more pathetic is that it appears you get no coins, at all, for the bundled Nintendo Land.
CN coins are nearly "free" for Nintendo, and they shovel them away for other things -- giving the same number of coins for the Wii U as the Wii is insane.
Ideally, the Wii U Deluxe set (with Nintendoland) should be worth at least 350 coins, and the basic Wii U worth 300. Something NEAR those levels...
Edit: The site also has info on linking Wii U Nintendo Network accounts with Club Nintendo.
