Back to this, I have a couple more things:
1. Ability to transfer game saves between profiles, either on the same Wii U or to a different one. That is helpful if your kids started with sharing a profile then decided they want your own, or if you are upgrading to a new Wii U and are not held back by eShop purchases.
2. A means of bringing your profile and eShop games to a friends house. I think the simplest solution might be to have a proprietary device (that's either USB or connects to the gamepad) that you can link to your account. All profile data will remain on the device which must be connected at all times on the friend's Wii U, with downloaded games either residing on the device itself, expandable memory (like a SD card) on the device, or your current USB drive.
3. a method of transferring your Nintendo ID and all account information to a new Wii U, without having to bring it to Nintendo. I think an acceptable compromise would be to either use something like the Wii Transfer Utility, or to bring both Wii Us to an authorized store (Like Best Buy) who can (possibly for a fee or Free with an new Wii U) confirm the transfer to the new Wii U, after which everything will be redownloadable onto the new Wii U.
4. Have the TV remote become a proper smart remote, where you can map and arrange the buttons yourself and manually program them. Then you can add buttons or devices not normally recognized by universal remotes. I'd be happy if I'd have to pay for this, as long as it's not too much.
5. Ability to change your Nintendo ID, even if it's a charge.
I'm glad to see the extended battery is coming out. it's good to have realistic expectations as you're hardly ever disappointed.
