Yeah, that's...really bad. The WiiU is still ahead of the other two in terms of sales, but it only sold around 1/20th of the PS4 and Xone's numbers. Pretty much a smoking gun for third-parties in their case for abandoning the platform. Hell, Declassified is one of the top selling games on the Vita despite being a piece of shit, and even that didn't compel Western third parties to keep supporting it.
Granted, I heard that the WiiU version was missing features--another trend for third-party WiiU games. But with such a huge gap, one has to wonder how much of a difference that would've made.
