They didn't even bother making a new side panel for it? My only guess is they had some spare parts from previous Wii models and couldn't find a better way to get rid of those. Very lazy move on Nintendo's part.
I first planned on getting one of these because they look really cool, but I probably wouldn't play on it anyway and after seeing it's just an extremely lazy rehash of the regular Wii, I'll save the money and get some more 3DS/Vita games.
Thanks for the information btw, I'd never read about this issue before.
