I think Example #7 is just an honest mistake. Joystiq doesn't seem to be anti-Wii judging from the majority of their blog posts/articles covering it.
another example would be 1up when they said Epic Mickey was not Wii-exclusive.

and I also remember them saying that Tatsunoko vs. Capcom was coming to PS3 and 360.
