It sold about twice as well, but the install base for the PS3 is about 8x bigger than the Wii U.  Obviously, that doesn't mean that it should sell 8x more, but the expectations should definitely be higher.  It also opened at about half of what GT5 did. 

So in your logic, if Mario Galaxy 3 was released on the Wii it would sell more than Mario Galaxy 2?

not necessarily, but opening at half the predecessor is not a good sign.
