We do know and it doesn't. There has been a good couple of decades of WiFi level frequencies being transmitted around the place, a good 50 years of signals from satellites and a good 100 years of radio signals in general. If there was a massive health impact we would have known about it by now. We can't even prove a direct link between mobile phones and cancer and that's with significantly higher powered signals placed directly at your brain.

Anyway, we already have it as "some global thing"... it's called satellites. We have GPS and we have satellite internet services covering the entire globe. The problem is as an internet service it sucks because the "towers" are all the way up in geostationary orbit.....

GO HARD COPIES!
Anyway, I wouldn't mind a revision later on, only because I'll probably end up buying a second Wii U late-lifespan some way or another.

yeah i may end up doing the same too especially if they did a special edition for legend of zelda a good wiiu or something like that of course then i would never open it but i must if i want to take the game out and put it in my deluxe wiiu

It'll most likely happen at some point. I wouldn't wait for it though, buying the original product seems to be the best choice.

Looking at the Wii MINI and Wii Family Edition they might be smaller (which is nice) but they also lack a LOT of features. Wii Family Edition isn't backwards compatible and the Wii MINI can only read Wii discs.. It can't even go online.
