kotaku.com: Since the Wii U was released last month, it's been unclear whether Nintendo Network IDs—the online username and profile for any Wii U owner who plays, communicates and shops online on the system—is forever baked into the Wii U it is initially registered on.
Users are not given any tools to transfer their Nintendo Network ID from one Wii U to another, but there is a mention in Nintendo's Wii U documentation that the current locking of IDs to one machine is temporary.
Besides, they've already confirmed that Nintendo Network and the IDs for them will become more universal (logging in through computers, smartphones, etc.).
i tend to have multiple systems with the same account on them. Either that or I make a transportable profile on a flash drive.
In this case, i plan on getting both the black and white wii-u. one for upstairs that the kids would play on and one for downstairs for me or the kids to play on.
seeing as i am the one that makes purchases i would like to be able to log in to either unit and buy something for everyone to play. i basically do this now with multiple 360's and PS3's.
When it came to the dsi and 3ds, it was rather unfortunate that i couldnt just sign into the eshop on the 3ds and be able to download what i had paid for on my dsi. Doing the software transfer process moved the games from one to the other but it would have been nice if there was an option to just redownload what was already purchased instead of transfer.
I myself would liked to have been able to play the same game on either unit. Its as if the points and account really arent tied to you but the system and they will get that all sorted out sooner or later. hopefully sooner rather than later.
You can only have 1 SYSTEM per account, not the other way around.^ͺ^
Good thing they are acknowledging it.
Why Nintendo opts to use such an archaic online infrastruction is beyond me.
Nintendo needs to fix up if they want to compete in the online world.
