EA has confirmed we will be using our own Nintendo Network IDs to gain access to Wii U’s online play. EA’s privacy policy states that we will need to send our IDs over to the gaming company so that we may be linked up to its Origin service.

If you sign up to play EA games through a Nintendo Wii U console, your Nintendo account information will be provided to EA so that we can establish an Origin Account for you. You need an Origin Account to play EA’s titles online. By signing up to play EA’s titles, you agree that limited user account information can be transferred to EA. Information transferred to EA includes your Mii information, email address, Nintendo Network ID, friend list, country, language and date of birth but does not include credit card number or other financial account information.
