We are going from one corner of impossible to the other... from PS4 or Xbone outselling wiiU before March 2014 to WiiU outselling both... this is a case of Gaussian curve, where most of reasonable people will be in between...
And sony forecasting they expect 5M don't mean they will meet it, but also don't mean that it can't be more (unless they also state they can't make more, which they kind of said when stating they are in full production).
WiiU will be in 6~8M range (i believe closer to 7.5M because of the 8 great sequels/remakes) anything bellow or above will depend on conjecture of factors and a large unforseable.
