EU Nintendo sites list Mario & Sonic at the Rio 2016 Olympic Games Wii U for August 9

This is a weird one. Various European Nintendo websites list Mario & Sonic at the Rio 2016 Olympic Games for August 9, 2016. While this is only for the download version, the listing still strikes me as odd. Tuesdays isn't usually a day where things get released in Europe, as download and retail games get released every Thursday and Friday respectively. Another thing is that, if the date is actually true, the game will go live after the Olympic Games have already kicked off in Rio. We can only wait and see what happens at this stage!
