The WiiKey website has been updated as of May 18th 2014. It now says:

''We will start taking Wiikey U preorders in the next week! A lot has happened recently and we are now confident to launch Wiikey U! You can look forward to other exciting WiiU news in the coming weeks...''

Isn't this HUGE news?! Yet I can't find anything about it on any forum. Thought I started a thread about it since this might mean that big things things are about to happen
