Up 11,000 units in the US this Q.
However Worldwide it is down, as Japan has seen a big drop
Japan

Down 63k YOY.
Europe is an unknown, but it is A) by far WiiU's weakest region but B) trends like the US, so it could be down, flat, or up, but either way it won't be by much, not enough to offset being down 52k WW.
So partially good news for WiiU in the US, at the least it's stable, but not so good news in Japan and overall, Worldwide.
