If you own a DS/DSi or a Wii and you like playing games online then you are in for some bad news as the Nintendo will be discontinuing the online services for those consoles as of May 20th, 2014. This will be very upsetting if you are a Mario Kart DS/Wii fan, a Pokémon Black/White or Black2/White2 fan or a Super Smash Bros Brawl fan.
